That's easy to say, but nobody is stoping you or anyone else that thinks that way from building yourselves a home deep underground. There's no real engineering challenge, we know how to dig very big, very deep pits, the problem is the costs are astronomical relative to conventional housing. Not to mention the huge energy cost and thus carbon footprint of that kind of construction. It's conceivable those costs might be reduced, maybe the Boring Company will find a solution, but the fact is it involves moving an awful lot of very heavy material.
