The only consumer survey they actually reveals preferences is the price that people are willing to pay. Ask them questions in isolation and you miss all the implicit tradeoffs inherent to the questions.

And on that front, prices in dense areas are way way above suburban areas. Even if you subtract the lawn. People will pay far far more per sqft for a home in a dense urban area without a lawn! Which indicates that dense living is far undersupplied.

Not coincidentally, we don't have to ban suburban living, we only ban dense living. Literally anybody could buy an apartment building, tear it down and build a single family home, but how often do you ever see that happen? But you can't go the other direction, by law.
