I wish it worked that way, but from my nearly 20 years of urban land use policy study and writing, I have seen tons of evidence that it does not.

The problem is that the most in demand areas get new buildings at 4-6 stories, and then you get locked up - the airspace above them becomes unavailable for 50-100 years, when there was market demand for some taller buildings from the beginning. It's the same "push down and spread out" that causes sprawl, just more localized.

I mean, yes, when the incentives are the literal opposite of this policy, the the outcomes will be the literal opposite of what we want.

People respond to incentives.

It takes an awful lot of incentives to knock down a "usable" structure. I'd love to build higher-density right here, right on my lot, but unless I squeeze something in on the same lot, I'm out $150k just to start. $150k covers quite a bit of gas to the lot 2 miles away that's empty.

		> It takes an awful lot of incentives to knock down a "usable" structure. Yes, that’s the point. The policy only really changes things when prices become extreme, and the cost per unit of housing becomes completely detached from the cost of building that same unit. This is trivially happening in much of San Francisco and New York City.
