I agree with all of that, but I think there is additional nuance. I would love if the path were as simple as:
(1) Make housing easier to build.
(2) Receive sufficient housing supply.
Even if you make it easier to build houses, there is a market for the capital that housing developers access. Currently, that market also assumes that prices will go up (or at least not go down). Thus, once we go far enough past the point where existing prices are higher than the return on new housing, even all of our dream reforms may not lead to a flood of new housing starts.
I want to be clear: loosening zoning, reforming regulations, and so forth, are all still worth doing. It is better than nothing. But if the result is a shock of supply, the financing for new homes from the biggest players will dry up. That doesn't make a solution impossible, but it does complicate it.
