Article here interviewing the old L5 member.

“I am for a dramatic increase in our efforts to reach out into space, but I am for doing virtually all of it outside of NASA through prizes and tax incentives. NASA is an aging, unimaginative, bureaucracy committed to over-engineering and risk-avoidance which is actually diverting resources from the achievements we need and stifling the entrepreneurial and risk-taking spirit necessary to lead in space exploration.”

I think that the post Apollo record for NASA in crewed spaceflight speaks for itself. Retreating from cis-Lunar space, orbiting round & round John Glen style including a glen redux bogus mission, frying astronaut crews in the death-camel known as the shuttle, spending close to $100B on a space station that's incomplete and produced less new knowlege than 70s Skylab.
