This is an interesting way of framing the demographic problem, yes. In the US for example, from WW2 thru roughly GFC, working age population grew faster than the retired age population.
So there was relative political power in the working age, and a large/growing group to sell houses to. Further, pre-GFC there was a big trade-up market even for existing homeowners.
Now demographic & politic power in the west are in the hands of the older, homeowner retired/near retired baby boomers. Incentives to reduce the value of their largest asset are not strong. Also this is why we keep electing dinosaurs in the US.
