Stop densifying cities and start building out suburbs where the land is cheap.
Using all kinds of regulations to ignore the market signals usually points out that you're doing something wrong (not _always_).
Except regulations are what got us here in the first place? At least in the US, zoning is a recent invention with racial motivations. Cities want to be dense because that is the cheapest way to build. That is why basically every city older than a 100 years old that hasn't been wrecked by zoning is dense. Suburbs are an unnatural product of abundant land in the US, the invention of automobiles, and zoning.
Too late in certain markets like LA. They already built out all the flat land for the most part by the 90s. Only way to go now is to go up. There is no more land to go out. Look at the satellite map, development from ocean to mountains.
