To summarize, you argue that it's a supply-side problem and not a demand-side one.
The only loss when building more dense housing in urban areas is the existing owners whose views are blocked. Otherwise it seems to generally increase the tax base, support more businesses (when mixed-use housing is built), and increase renter mobility.
It is a lot about more supply (and less price increase, or even decrease). Not about views being blocked. People who own homes feel the need to defend the price of their prized asset, for which they have used their life savings plus leverage. The system is designed to perpetuate itsself
