I think that's a pretty wild take given the state of NASA right now. The only way I could see anything like that happening would be the GPS model, where the DoD build out StarShield for military purposes, then realise it'd be a net good for civilians to have ubiquitus global internet services. Even then, that would compete with existing non-SpaceX services which is antithetical to NASAs principles and would be considered 'socialism' by half of America.

Asteroid mining is really in the hands of governments. While space is basically a free-for-all on an international level, each nation can levy whatever conditions and taxes they like on their own enterprise. If companies tried to 'flag' themselves with low-tax nations, then I think other nations could levy tariffs and prevent access to technology to make that unattractive. Either way, a significant portion should end up in government budgets.

I'd rather private equity invest in more forward looking technology than LLMs or finance. There just needs to be a balance where it's still attractive for them to invest, but as much of the value as reasonable gets distributed in lifting up the quality of life here on earth.
