They have already done this with near I guess, but in a way you are making
the opposite point o which you claim. I think the idea is to set up shop on
the Moon now, and use it as a staging post to other places.

The moon is a terrible staging point due to its gravity well. I'd think
an earth orbital station or a station at a Lagrange point would be far
better.
