Aside from being a sentence fragment, this sentence is wildly weird.

Look at cities that have no zoning, like Houston. They are horrible places to live, and they are absolutely no more hospitable to homeless people than any other place.

The idea that if zoning were removed then people would build huge quantities of low income housing is bizarre and unintuitive, and you don't explain at all why that would be.

Don't get me wrong - there is a trouble with "zoning" in the United States and that's that it is run by "selectmen" and similar anonymous elected officials who treat it as a way to steal money from the public.

It's a shame that you started off this otherwise excellent article with this peculiar libertarian fantasy. I'll still clap though. :-)
