The biggest thing limiting the colonization of space by private interests is the vaugness of space property rights because of dumb idiotic “feel good” measures put in place by the U.N. over the last 50 years.
I say if you can maintain a permanent base on the moon with an ever increasing population you can claim the land around the base within a 100km radius or something like that.
Rather than the feel good crap that “the moon belongs to no one” shit that has been fed to us by the UN.
The UN is a joke. "How" are they going to enforce? This is not to say that the "legal" limitations should be eliminated.
