One of the necessities is cheap access to the orbit, and I just cannot see the national behemoth space agencies developing economic, reusable rockets. The traditional rocket industry in the US was unable to do that either.
The barriers to becoming an agile space company are formidable. When looking at SpaceX, we forget how many space startups from that period are now defunct and forgotten. John Carmack founded one, too; it is gone.
An interesting fact is that they did very well as long as they could conduct cheap tests very often. As their rockets got bigger, they could no longer do that and then they floundered.
Was there a good enough reason to go again?
In contrast, there is a good reason to have re-usable rockets and quick deployment now.
Star-Link and reusable rockets now have tremendous military uses which are being demonstrated in Ukraine.
Monetary concerns will take a back seat to that.
Heck the Pentagon probably has a plan B in the drawer for a Starlink-like constellation dated fall 2022 should Musk go more unhinged that he already is. LEO constellations went from ‘interesting’ to ‘paradigm shift’ overnight, nothing to be surprised about.
