Very much this. There is no cabal of homeowners opposed to lower prices despite it being often repeated. People buy a house to live in it, they're not paying attention to who is building what. Also nobody is asking homeowners opinion on what build sites get approved or not. If there ever was a proposition related to housing approval it would be in the ballot open to all citizens. Early in the history of the USA only landowners could vote, but it's been a very long time since that's been the case.
