As far as your implication that Houston's lack of zoning makes it an 'almost anything goes' place, this is 100% false. Houston technically has no zoning laws, but while that has ended up in a few kind of wacky situations of a small house next to a large parking structure, those are the rare exception rather than the rule.
Houston has a lot of ordinances, deed restrictions, density rules, setback rules, historic districts, parking maximums, etc... that basically provide the same regulations that other cities just lump in under zoning laws.
Saying Houston has an anything goes zoning policy implying it's the wild west of building is completely wrong. It's just a play on words that is very misleading.

The thing about Houston is it is pretty much like many other cities in the country, with both some good attributes, but also has pretty much all the same worst attributes of cities with zoning laws that have accumulated insane sprawl, like Los Angeles, and have become completely auto-dependent cities unfriendly to walkability, other non-auto forms of transit like bikes and have terrible mass transit systems and lots of segregation based on class and race that is a direct result of those very rules and regulations and ordinances. At least Los Angeles couldn't build high because of earthquakes and lack of engineering to combat that back in the day. Although chances are it may have ended up in a similar sprawl situation, but we'll never know.
One thing Houston might need zoning for is it's murder rate. It's 2x as high as Los Angeles and 3x higher than New York City in the last year. Maybe they should have a zoning ordinance against murder?
