What scarce factor of production stops them from churning out more ships? Skilled labor? Industrial output? Personnel to man their ships? Expensive, hard to produce technology? Are their shipyards difficult to construct? Difficulty lifting parts into orbit? A shortage of raw materials or a difficulty in transporting said raw materials? The expense of producing antimatter? Or, simply a small military budget?
The small size of the Starfleet compared to their population, about 1000 ships with average length of 350 meters, or roughly the volume of 100 million tons of modern seagoing warships, can be explained by minimalist bias.
Today the world's merchant fleet has 1.1 billion tons:

And South Korea produces 12.4 million tons of shipping per year. That's the size of 150 carriers of 300 meters in length. Comparable to the total annual production of the Federation.
The 1 trillion figure is canon? Because there is nothing in ST that implies that the population of the federation is more than circa a few tens of billions.
Any insights or speculation would be appreciated. I am asking because I am trying to concoct fleet-strength figures for a hypothetical Trek nation, and want a more thought-out limit than something like "as many ships as the Klingons have."
I would think that an civilization with 150 worlds would have a population of 500 billion, a Starfleet of 50,000 warships, each on average of 550 meters in length (that would give a size of 25 billion tons in terms of modern seagoing ships) and the capacity to produce 10,000-20,000 such ships per year in case of war. That's my low end estimate for the size of the fleet of starships.
The size of the merchant fleet of a 500 billion people interestelar empire would be at least in the hundreds of billions of tons. More probably in the trillions.
