> The poster you're replying to still has the cause vs effect right. That gets encoded into law because that's what a lot of people want. The law follows the demand - people know that there are developers out there with far more money to throw around then they have, so they fight money with law.

This doesn't make sense to me. If single-family homes are what most people want, why would a developer bother to buy up land and build something denser if people don't want to live somewhere denser? That sounds like a dumb business decision.

Nearly the entire country is zoned for single-family housing. Someone who wants to live in a SFH has no shortage of options. Meanwhile, someone who wants to live somewhere denser has very few options; we've almost entirely banned building new ones, so what dense places do exist are mostly the ones built prior to modern zoning codes.

As a result, people who do want to live somewhere denser often aren't able to, despite the demand. The data backs this up: https://cityobservatory.org/the-myth-of-revealed-preference-...
