The Free Enterprise option means supporting privatization of the space program. NASA's first Administrator Dr. Keith Glennan envisioned NASA as an R&D organization with no operational role in space transportation. This is a return to that model. It defines the government's role as supporting and encouraging private industry, but never competing with private industry. Private ownership of space assets is the policy. Private property rights in Space are supported. Your three choices are:
Sell the Space Shuttles,
Set a future date for privatization of space transportation,
NASA develops space for industry.
