> In almost all cities land has run out, so the only way to actually increase supply is to increase density. That means fewer single-family-homes, and more townhomes, multi-family, condos, and apartments.

Existing property owners can only afford to hold this opinion because land rents are insufficiently taxed. Through some sort of monumental stupidity we decided to tax labor instead of land. In this sense the SFH, “Americans like suburbia” problem is just a function of poor tax strategy. If homeowners were faced with the economic reality of their choices then markets would fix land use by themselves.
