I agree with everything you wrote. I'd like to add the pyramid angle.

Fancy mansions have always been overpriced. For property prices to grow faster than inflation, the pyramid needed to grow its bottom. Supply restrictionism was the ticket. Eventually, every shack was priced mansion-like. This required extracting ever larger fractions of the incomes of renters. Some renters wisened up and bought homes (when they still could). Changing sides, they beefed up the scheme's political backing.

No one cares if mansions are expensive, but basic housing should be extremely cheap. This sounds like a handout but isn't. It's what an unadulterated market would provide. It's what the pre-1970 market used to provide.

That's not to say that markets should be left alone. It's to say that the way this particular market was "regulated" was fundamentally corrupt. We could call it negative regulation.
