was talking about this with a friend who knows more. He did point out we need to replace old housing stock, which we also don't do, so just have cold, mouldy old houses. But that's not what's being talked about here.
I also had a twitter conv with a housing charity once, who agreed but pointed out that the financialization of property is hard to overturn, and it's easier to just advocate for more building. Problem I see here is that the new buildings will just be more stock for existing portfolios, and actual prices don't seem to reduce.
