>long term you want to use those rockets to put the people, Sure, maybe in very limited capacity, like why not build stuff in giant parts like giant lego blocks on the planet and have some robots and a few people assemble it in orbit. Rather then have 10K people work extremely inefficient and dangerous in zero gravity(I am assuming you mean we capture asteroids and we build stuff from bare minerals up). Imagine what extremely expensive factories you need that work in zero gravity(things fly everywhere at a small bump) , so maybe first we build a giant rotating space station using parts made on Earth. In the long term we should have better rockets , maygbe we pt a space station in the important points in our solar system and send them this big lego parts so they can just assemble them. Personally I see no way humans can live and work more efficient in space compared to live and build stuff on Earth and pay some guys to build big rockets and move the stuff into space, even in long term. What we are missing today is the ability to have guys present when the telescope unfolds to help with problems and manually do fine calibrations, if we could have that we could build a giant mirror made from small parts and have people just help connect the parts
