I think that having a space station around the moon would be beneficial, but it would be better if we had space stations coupled together in a way. If we had space stations that could launch space craft to the next, we could create a space elevator type system, with each using inertia to launch the craft at a faster speed therefore allowing it to travel farther. That would allow us to move faster between stations, and farther, after exiting the last space station. Eventually we could launch craft far enough to reach a Lagrange point or, as Buzz Aldrin proposed, A cycling spacecraft. That would allow us to launch lighter spacecraft, therefore conserving fuel and using gravity to boost it along, as we have in the past with the Voyager spacecraft and the New Horizons probe.
