Earlier quoted context omitted.
We seem to be going in the opposite direction of a “post scarce” world where everything is getting more expensive and most people I know are working longer hours or multiple jobs to survive.
Any world that includes a scarcity of a necessity will have people trying to outcompete their peers for said necessities. Right now that's housing, for the most part, and sometimes health care. Sure you could ask for a 4 day week, but someone else will work 5 so they can outbid you on a house.
Human preference is also wildly variable. I don't buy the constant "I'd rather not live in a city" argument that we hear because people could in fact do that, but there are plenty of preferences that people do make and it isn't like housing in fungible.
The simple model won't get us very far in estimating the actual effects and likely will actually make us make the wrong conclusions. Plus, there are solutions to many of the housing problems (which also is non-singular).
