Hey man, I think you're off base here.

The problem is that the Moon does not have significant resources, so you can't really make anything on the Moon and then launch it from there. It may be possible to make some propellants, but not much else. As a refueling station, it could be a good idea. But for anything other than fuel, the Moon doesn't really work out as you have to lift it from LEO first. Entering Space by Robert Zubrin has more detailed technical arguments about this.

It's my understanding that there are irons and titanium ores on the moon as well, though I do not know in what quantities.
