Houston has zoning if we define zoning as "rules that define where you can build, what you can build, and what auxiliary details you must include". They just don't call it zoning.
More importantly, near everyone arguing for change in zoning aren't saying that zoning should be abolished, just changed. So, Houston is not a counter-example.
