And again, supply will always be constrained below "affordability" by virtue of there being no profit available at affordable price points given the costs of inputs. So yes, if we imagine a world where supply isn't constrained first by the actual cost structure of construction, then clearly artificial constraints are the sole problem and solving them would solve the problem overall. But that's not the world we live in!

From your random paper:

> Fig. 5 shows the event study results for the change in log hedonic rents. In contrast to the housing supply, we find no statistically significant effect of upzoning on rents.

So it looks like your paper actually agrees with mine.

As I've said over and over: we should overhaul zoning for sure. However there is not good evidence that will solve affordability, and there's basically zero evidence that it is the cause of "all" the problems, as you so boldly claimed.
