It's a very old Idea. Metropolis, 1927

For the rest of us, Hell in steel and concrete, aluminum and glass.
Cities breed rules. People who live close together (especially from different cultural backgrounds) seem to need rules, and they go apeshit making them to the point where no one can follow what all the rules are, much less abide by them. A segment of that society will then do as they please, just because they can't follow the rules anyway. There's plenty of that going on today. The result is that the people making all those rules either ignore them, or go all-out Nazi trying to enforce them, and ever making more rules.
That's where our cities are today.
I don't want to live in any city, but if anyone is determined to build something like this, how about a pilot project before going hog wild into production?
