Almost any reason why the moon is better than in orbit is a point for putting it on earth.
I have long theorized there will be some game changing manufacturing processes that can only be done in a zero gravity environment. EX:
- 3d printing human organ replacements to solve the organ donor problem
- stronger materials
- 3d computer chips
I do not work in material science, so these crude ideas are just that, but the important part I'm getting at is that we can make things in space without any launches once that industry is bootstrapped.
Either way, this isn't about 3D printing organs, this is about launching AI compute into space. To do important stuff, like making AI generated CSAM without worry of government intervention.
