I am just honestly confused. There seem to be no logical reason for it, except that it would raise the stock value of rocket producers like SpaceX and Blue Origin.
There is zero economic reason. Most optimistic cost estimates are 5x more expensive than earth systems powered by solar and batteries. With near term optimism 10x more expensive.
The only reason is skynet that is immune for anyone in the US pulling the plug from skynet. Russia/China can already hit sattelites or terrestrial datacenters with missiles, and space ones are more vulnerable because Americans are more likely to cheer destruction of skynet assets used to oppress them.
The other factor is international law permits squatters rights to the most desirable orbits. 300 years from now, we may need power/data beemed to/from space. Privatizing it for oligarchy is a great long term investment if it is subsidized by US government.
