They are all much more dense than the bay area, and I don't get the sense that many people want them to be denser other than, again, for affordability reasons.
I don't have data but in Moscow where I'm from the typical well to do thing was moving to a "cottage village", something between a suburb and a gated community, despite good transit and horrendous traffic. In the 90ies it was stereotyped as a nouveu riche thing but in 2010s I even knew a senior dev who did it as it became more affordable. When I was visiting Tokyo iirc most local devs I was working with lived in the city but their manager lived in an outlying less dense area, since presumably he could afford it). I get a sense that people are likely to move to have more space and privacy, unless it's locally difficult or expensive.
