What Oregon did here, massively increase the supply of buildable land in one fell swoop, is pretty much the antithesis of those shortages you talk about there though.

The trend for cities in the past 75 years has been to down some continuously until there's not enough spare land that's zoned to account for the necessary population growth. Then, in that highly supply constrained environment, use political processes to upzone only a tiny amount of land. Typically this is the "blight," the few places that minorities where allowed to live when racist deed restrictions were allowed, the areas where city services were less, and that stayed that way.

Societies would take the most undervalued land, force the huge backed up pressure into these vulnerable neighborhoods, and let the few lucky developers that were politically savvy enough to navigate the process make away with the profits.

Now that it's everywhere, there will be more competition between developers and there will be far less exploitation of an artificially restricted resource. Land is already restricted enough, zoning for density just makes it all the more scarce and exploitable by the powerful.
