Fair, but the root reason for many of the core zoning codes is that the WW2 and Boomer generations felt that cars were the future and that low density car-oriented development was the only kind of thing they wanted to be allowed near them, mostly for aesthetic reasons and also because they perceived (accurately at the beginning) that “those people,” meaning criminals but mostly just low income people, wouldn’t be able to follow, and thus they’d have their idillic suburban life. So when we examine those root causes it turns out that they’re pretty crap and we don’t need to keep them around.
