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.
