Cities serve a purpose as a centre of finance and economic power output. They were founded on rivers and the coasts as a means of export/imports. I'm sure the founding fathers of London, NYC did not expect them to grow to the size we see today.
Humans rely on a hub for activity - which could be anything.
If you squared off cities to combat whatever ills you believe them to have you're just making the problem area larger and not addressing the one thing creating the problems, which are humans.
Lets take a look at the homo scene of two cities, San Franc and London. San Fran is notorious for this and the city/state has enabled this behaviour. They came together to fuck each other. You don't find communities of homos way out in the sticks because it doesn't serve their needs.
London has Soho and many other dens of degeneracy but again, it serves a purpose and fulfills their needs.
You'll never solve the problems of any urban area with a lot of people by re-designing it.
