The moon is a delicate object.
Despite what people fantasize about doing, We can NOT mine the moon, or built large structures on it.
Because it is the moons precise mass and weight that keeps earths orbit in check.
It would be far to risky to do anything worth while with the moon, Without risking damage to the ecological cycle of earth.
Now, small stations or what not probably won't hurt...but it takes so much time to get to the moon, not only that...but the moon is not protected from radiation.
For the most part, IIRC, the ISS and Shuttle orbit low enough for them to be protected from the vast majorty of radiation in space by the earths magnetosphere.
