Good points, roachboy.
I'd say at this point, the highly risk-averse culture we find ourselves in and the extra restraints put on NASA in terms of public relations and budgetary requirements make the rapid advancement of man-in-space technology impossible now in that venue.
Curiously, we have a situation where the government can not fuel the populist vision of the possibility of space flight for anyone but the military/elite crowd. As an antidote to that, private enterprise is able to offer up the promise of low-cost and accessible voyages into the Final Frontier. It's a uniquely contemporary solution that is an undeniably a good and inspiring thing, I think.
