The moon may be an illusion and hasn't really been there at all.
The 'moon rocks' containing minerals not yet known to exist on earth, could simply be a recent discovery on earth, kept secret.
After all, we are only talking about some 2-to-5 thousand people involved in the whole thing.
Keeping them quiet is a piece of cake for NASA and the rest of the government. Probably a lot easier than going to the (virtual?) moon.
And,,, it creats jobs and new businesses.
But,,, my warped logic is microbic in size... Maybe I need another beer...
