Space habs buried under the moon's surface

And then there are the energy costs to keep the thing spinning.

Even with magnetic bearings, the energy costs are thru the roof.

Back to square one. The idea of habitats of a permanent nature on the moon or mars is ludicrous compared to asteroids.

Having the moon and mars for recreational purposes, a sort of landing site and socialization center around which we park the asteroid colonies is a fine plan.

But trying to deal with making artificial Gs on a lunar or martian surface turns out to be a giant engineering problem with even more enormous energy costs.
