So problem will never be solved then. Far too much vested interest in the status quo from existing landowners.
Nobody is going to build “affordable housing” unless you like living 10 hours commute from major cities. And as soon as someone builds a bullet train to shorten the commute to an hour the prices will skyrocket.
So I’m going to put it a different way that you absolutely won’t appreciate but is the truth.
I’m a homeowner (single detached) that has a significant mortgage. Anything that happens to lower prices is going to negatively impact me so I don’t want change to bring property prices down now, but to have them go up as high as possible so I can sell down the road and make money.
That’s what you’re dealing with. It’s not defeatism, it’s people actively voting against and impeding stuff that will go in the direction you seem to think people want. Many do not want change in that direction at all.
Preparing for downvotes from those who don’t like cold hard truth.
