And housing should not be a free market.

Agreed. We should regulate it. First, we should zone areas of land as only being for certain types of homes. This will ensure that the detached mansion you always dreamed of will not be usurped by some developer wanting to build condos. Next, we should regulate the structures so that someone doesn’t try to build a small/tiny home where you want your glorious mansion. Third, we enforce only one structure per property. Your mansion needs a sizeable backyard for your pool! I have more ideas, but think that’s a good start.

Oh wait.
