I countered by saying that while Mars Direct might cost $30 to $50 billion if implemented by NASA, if done by a private outfit spending its own money, the out-of-pocket cost would probably be in the $5 billion range.

Not only that, but just about every modern thing that drives our economy today started or got a huge boost from two things: WWII and the Space Race.
There is a legit Constitutionality question, but this would be an economically and technologically stupid place to draw that line for the first time since FDR.

Or gut the muslim outreach program calling itself NASA completely except for this...
The taxpayer-funded prizes are the problem.
