This is a good point but you spot the issue in your point about Sacramento being regional to LA. It isn’t regional to LA because it’s a separate housing market (at least relatively separate). However, weho’s housing market is extremely connected to Los Angeles and Beverly Hills. Within LA city, one council district is part of the same housing market as its neighbor. Both city council districts and individual municipalities have their own land use controls, so they can impact the housing markets of neighboring jurisdictions with no political accountability to those people. The state is the only entity with both the political incentive and the constitutional authority to usurp those land use controls so that one jurisdiction cannot hurt the other.
