Again, the Ferengi are a bad example since they aren’t part of the federation. But my point was simply that this stuff wasn’t thought through. Why do the Ferengi exist? Because the writers wanted some capitalists to use as a contrast to the Federation.
I firmly believe that ST’s worldbuilding mostly handwaves the questions of economics and scarcity, at least within the Federation. The writers didn’t want to come up with good reasons for these things that actually make sense when you think about them.
It’s a great franchise, but we shouldn’t try to apply real-world economic ideas to it when that was so clearly not at the front of the writers minds when they created it.
