That article mentions arming space, not arming the moon.
Also about Helium 3 on the moon, I read an analysis about that in a book ("Mining the Sky") that was generally enthusiastic about getting resources from space (as you can no doubt guess from the title). Basically, the chances of lunar helium-3 harvesting ever being profitable looked slim to nil even if there was already a base on the moon to use. However, the book did provide an interesting case for it being potentially profitable to get Helium-3 from the atmospheres of outer planets such as Uranus.
