So where would the garbage workers, waiters, construction workers, cooks, cashiers, and other people who work menial jobs live in your ideal city? On the streets?
What do you do for a living? You seem to have little regard for people not in the position to own property like yourself. It’s good for you that you have a (presumably) high paying white collar job that allows you to live in wealthy areas of town, but a city cannot function with JUST wealthy people, unless you want to pay garbage workers $30 an hour.
These zoning laws implemented in the first place in places like San Francisco are exactly why you have people shitting on the streets and making tents there, ironically enough. Zoning almost always makes cities worse off in the long run at the expense of very few property owners.
