You don't need man-rated rockets...
just to launch the inflatable test stations. You only need man-rated rockets to get the punters up there once the foothold has been established - so he has a while to get the Atlas V's brought up to spec or an alternative built.
Good on him.
The likes of him and Branson should be applauded for their attempts to Get Things Done. Despite what those with their heads in the sand might think, we've got to get a foothold in space and start using it for energy and resources or we're screwed down here. The more people and agencies (NASA, ESA etc) working towards that end, the better.
Donating his billions to "the poor" might help a few people now, but spending his billions on space research, habitation etc will continue to benefit future generations.
OK, so he hopes to turn a buck or two with it and make a profit - but that will not invalidate the usefulness of whatever technology comes out of his quest. And frankly, if it came down to the wire and only the likes of Bigelow and Branson had the capability (using their commercial enterprises) to put power stations in space and harvest minerals from asteroids, I'd merely be glad there was someone up there capable of doing it - what's the difference between paying them and paying my local power company?
