Well, a bunch of us are fully aware of the possibilities and the commercial potential for such a place, and many of us are also aware of the military threat presented by allowing potential enemies to establish primacy on the moon, also.
Seriously, the potentials outweigh the costs. What's needed now to exploit the solar system, starting with the moon, is basic engineering applications, not scientific breakthroughs.
What is the first necessary step in getting out there to find alien life?
Oh, that's right, the first necessary step is colonization of and exploitation of a major airless sterile rock orbiting the Earth.
