I’m not sure what this is supposed to contribute to the conversation. Regulations make it simply impossible for housing supply to keep up with demand in California (and lots of other places too). This point in particular is not even contentious as far as I can tell. If you want to fix the problem, the only way to do it is to relax zoning and permit regulations. Trying to fix over-regulation with more regulation will only ever make things less efficient, requiring even more regulations, ad infinitum. This has been California’s long standing policy, and not only has this never solved the problem, it’s never even been able to stop it from endlessly getting worse.
