That said, what surprised me here is how dangerous this is: Musk's Twitter is probably world's number 1 place for peddling Bitcoin scams. Anyone reasonable would of course immediately recognize the scams because there's no way Musk would have anything to do with cryptocurrency. But now, I predict a lot of folks will get scammed.
Why?
Who is “we”?
There's a reason that sci-fi with space flight is almost always more optimistic than sci-fi without space flight.
Can you explain your theory in the context of the American West “frontier”?
Of course the American West was not a pure frontier. It was already populated, so pushing West involved displacing other people. Space on the other hand would be a pure frontier, something that hasn't really existed on Earth for thousands of years.
A better picture of what you might get with a pure frontier would perhaps be Polynesian culture before colonization when they hopped from largely unpopulated island to unpopulated island. It would be more peaceful than the American west, more focused on exploration and settlement since there would not be conflict with existing occupants. Conflict between settlers is not even very likely due to the sheer amount of empty space.
You could argue that in the far future we might meet some aliens, but I'd counter that space is so f'ing huge that conflict between even massive civilizations would be unlikely unless it were driven by irrational motives.
"It's called space for a reason."
Also: The last round of space innovation was funded by two nuclear armed superpowers competing to show off while simultaneously threatening each other with a war of planetary annihilation. Before that the first rocket capable of reaching space was funded by Hitler. Going from blood soaked warlords to nutty manic billionaires is moral progress.
