And, well, what else... It can be beautiful.
A lot of this is compounded by the need for these homes in traditionally "private" environments - they're either located on in the middle of vast property, or on the edge of "unadulterated nature" (although the latter concept certainly hasn't existed since Manifest Destiny was invented).
It's just a lot of having one's cake and eating it, too. And eating it surrounded by glass. But located far enough away from the proles that no one will be watching YOU, certainly.
As a remedy, I suggest we return to underground bookshops and cramped quarters that make you feel like you're being swallowed alive. Where's the harm?
