Lets face it though - there's a separate problem and it is pretty simple - we just need more housing in places where the demand is high. Personally I think it would be especially helpful in the short term if there were big incentives for individuals to ADU's or inlaw units and things like duplexes, triplexes, or "bungalows" on one property. Easy sell for the public and would open up all of the single family home zones to much more housing and maybe even incentivize families across generations to live together again.
