Said with tongue in cheek, given all the complications you just
pointed out with that, right?  ;)

One major thing you missed: water tables.  Underground spaces
would get flooded easily (and irregularly), in many places people

people to move in, since most people won't move away from
establish supply infrastructure, and are correct to refuse to).
