>>> SpaceX is an amazing success story
100%, and something that is underappreciated and often taken for granted nowadays, especially on our little forum here.
>>> It would benefit even better by having many SpaceXs around.
That made me chuckle, sounded to me a bit like "our house would benefit from having a few cats around". Perhaps the reason why there aren't too many SpaceX-like companies around is that it's truly among the hardest companies to ever create.
If we're going to do public/private cooperation, we still need the whole competition thing.
If we don't have it, either we're subject to monopoly, or just a State owned company, at which point, why not just cut out the middlemen and go full Nationalized?
Boeing and others do complete in that area.
