There is plenty of evidence that housing supply is significantly limited by zoning regulations in lots of places. And in those places the little bit of construction that does happen tends to be targeted to the top of the market.

So I'm not just making an analogy. I'm reasoning from the available evidence.

The zoning laws aren't a product of government-en-vacuuo, however.

They're the result of moneied interests, most especially real estate and banking interests, constraining supply.

Government is the mechanism through which they act, not the source of the problem itself.

The interests in favor of zoning are almost all homeowners actually. Not sure if that is what you mean by "real estate interests."

Source?
