saving the energy output of an entire star.... what the hell kind of bucket does THAT fit into? How literally massive will the infrastructure for that be?
At a small scale where you're not using much energy but also not capturing much, it could be amassed in antimatter storage tanks of the kind Trek already uses. At larger scales, you may convert that energy into stocks of exotic matter you produced using particle colliders or store each as a small black hole that provides power and gravity to a space habitat. Alternatively, you could spend it by moving your star somewhere else, such as an unclaimed star system, and colonizing that as well.
How would you need more than just a fraction of a star's output to "build a crash fleet"?
How much more secure would the Federation be if they walked softly and carried a million ship string fleet as their big stick? Given how often Earth and other important planets are threatened by everything from Klingons to rogue space probes you'd think they may want more of a security blanket. You could also build trillions of tons of science vessels and explore space far more rapidly rather than sending a lone ship to get into amusing 'made for TV' adventures on a weekly basis.
This whole "save everything" reminds me of preppers that try to store 20-30 years worth of food in their basement bunker - if the situation is that dire you probably need to go somewhere else and you'd be better served by getting better transport than trying to stay in place. You're talking about saving entire output of a star over BILLIONS of years. How the hell does that work? Concentrate that much energy in one place and you have a star. You'd probably need a star's worth of some sort of mass to hold it. And you're going to store that for billions of years? WTF?
Just build some generation ships and leave already.
Why waste all that energy when you can use it for anything your heart might desire? Once you have automated space manufacturing building habitats, solar arrays, ships, are all essentially free so long as you can find the matter and energy. The real question is why we wouldn't use that capacity to fuel a level of decadence, scientific progress, and growth that can scarcely be dreamed of.
Seems to me that if you need phsophorus it would be easier to just, you know, mine phosphorus that already exists. Sure, it's a tiny percentage of, say, an asteroid but if you've got capture of stellar energy you just grind up/melt asteroids and other rocky/icy/whatever bits and extract that small percentage. Along with anything else already there.

So yes, we could pull it from our star or mine it from rocks, but there may come a point where just making it to order is easier. We're already facing issues with Earth's easily accessible supply and we may live on a very phosphorus-rich world.
As for latinum or dilithium... no one knows the physics of those things so kind of hard to comment on them.
If we can agree that they are made of matter and formed by physics within the fictional universe of Star Trek then we must agree that, theoretically, they are as open to being created in a lab as any other naturally (or unnaturally) occurring chemical and element are. Hence you can literally throw compute cycles and scientists at the problem until you solve it. This is another thing large populations are good at simply because more people equals more chances to raise and educate the next great thinker and having a billion Einstein or Hawking level thinkers who can work together means solving new physics questions faster.
Um. Yeah. A trillion years from now no species currently in existence will still exist just because genetic drift over that time span would cause sufficient mutations everything would be something different by then. Or, in the Trek 'Verse we'd all be energy beings by then with no need of stellar energy capture and would probably be off to a different dimension or building a new universe.
Most parents won't outlive their children, how is this any different? If you say that's different I could as easily point out that lines between species are pretty arbitrary anyway. There was no sharp divide between humans and our last common ancestor where we suddenly stopped being them and started being us. We just don't have the data to see every gradual step along the way so we only take notice of the big changes. How would an immortal AI see things from a god's eye view?
You still didn't answer the WHY.
WHY build a Dyson Sphere or Swarm? How is it inevitable? It's hardly the only imaginable alternative to living space in space.
What do you gain if you don't build it?
No, it's not. If you don't use a rock it is still a rock - unless you're talking about so far out there's proton decay in which case solar energy capture and storage will take a back seat to more pressing problems, like whether or not matter even exists anymore in a form that can make up a living body.
That's only true if you drag those rocks with you, which is another reason you might want to use the gravity of a star or artificial black hole as a means of storage. You can chuck those rocks or rogue planets into orbit around your power source and use them as needed. If you leave those rocks, photons, or energy differentials behind they will be lost to you.
You totally haven't read the bits about "maybe some people will want to live on a naturally formed planet", have you?
You know, some of us appreciate the scenery formed by happenstance.
Why do you rule that out? You don't even acknowledge the possibility.
Where did I ever say you
can't still do that? I personally think it's a waste of resources to keep planets around but until you get to a state where stars no longer form there's very little cost to setting aside habitable planets and stars for the small fraction of the population who'll want to live there. That said, I suspect that it will be a vanishingly small population in the scheme of things as once you hit the tipping point and have more people in space than on Earth living and dying in a habitat will be the new normal.
I sure as hell don't - coal plants are nasty.
I'm much rather live at a considerable distance from a coal plant (if we have to have them at all). I'd prefer not to live where the power-generating mechanism of my civilization blocks out the sun, sky, and stars. So why the fuck would I want to live in a Dyson Sphere?
So you're a fucking space NIMBY and want your personal preference for having a planet and star as the human default to override a more efficient way of doing things... If your argument boils down solely to some naive naturalistic bullshit I think we're done here.
But I don't want to live in an artificial "hab". I want to live on a naturally formed planet! Why do you assume I want forests? I'm allergic to trees! Give me a nice, red desert like Mars - love those wind-eroded rock forms! Or maybe I find hydrocarbon lakes and an orange sky fascinating, let's go to Titan!
You're assuming that people WANT to live in massive artificial structures. A lot of people DON'T. They really, really don't. Maybe they like living in a slightly challenging environment. Maybe they like the ways the stars look at night. Maybe they're just a stubborn cuss.
On what basis do you assume everyone else will like and want what YOU want?
We can look at history to see how this will go. How has urban expansion changed population distribution since the renaissance? Why do you think it will be any different when it comes to living and working in space?
Again - why do you assume I'm looking for 1g?
A lot of the problem here comes down to you making assumptions, to be honest. You talk like all of this is self-evident and it's not. Some people LIKE living in a desert. Some people LIKE living on the sea-shore. Some people LIKE living inside all the time and some others can't stand being inside.
Like I said - The Culture with it's MANY options makes so much more sense than you're assumption that automatically everyone is going to live in a Dyson Sphere in the future.
Quote me on that. Show me where I said that EVERYONE will live in a Dyson swarm, a solid shell is fucking stupid, and that each hab in that swarm will seek to replicate a specific Earth biome. You can as easily have whatever biome you want as well as somebody is willing to build it. You can even leave some unpopulated as parks if that floats your boat.
What I'm saying isn't that everybody will want this. What I'm saying is that space can support populations so vast that the small fractions of fractions of percentages who like planets will have so little say that they may as well not exist. You'll be the uncontacted tribe of the world, unimportant and doomed the moment we stop trying to preserve you and your way of life.
What if all you want to do is live on Mars near a kick-ass rock formation you can watch at sunrise and sunset?
Not to mention we're already exploring particle physics, the birth of our universe, and I believe the Hadron collider can make teeny weeny black holes (they evaporate quickly due to Hawking radiation because they are that tiny) with our primitive, definitely less than entire-stellar-output machines already. You don't need the entire output of a star to do those things.
So why are they already planning the next more powerful collider if this one is all the collider we'll ever need? Even if we don't NEED more power, why swarm up a few nearby stars and try some big bang level and beyond particle physics because we can? Worst case you can use all that energy to build something cool or spell your name in the cosmic background radiation.
Again, the assumption that everyone wants something artificial - what the hell happened to experiencing the real world, with all its faults and limitations as both a challenge and something to discover?
Why care what you want when the far more realistic likelihood is that your vision of a utopia will only be shared by a vanishingly small minority of luddites? It's like saying that because the amish exist we should stop building cities.
What the hell do you have against nature?
What do you mean by nature? The random, to us, distribution of mass and energy in the galaxy, life on this and countless other world, some spiritual woo-woo bullshit about god creating a universe for us...
Nothing about the way things happen to be right now is sacred to me. Humans aren't meant to live on planets because we're not meant to do anything. We're the result of physics and be those physics random or predetermined none of that combines to give the universe purpose or humanity free will. My opinion may change if we figure out what makes consciousness arise from matter (if it does arise at all), and by which mechanism that mind makes choices (if it makes choices at all). Until then, my belief is that we're but cogs in a cosmic machine and thus we may as well strip the machine bear and see what that does.
