Jebus you watch too much sci-fi, MediaBuysEyez....
It's pretty obvious what would happen to them if Anarchy took over soon:
1. They'd be offered free market education... Surely a few would bite, and tell their families, and eventually (maybe a generation later?) they'd all see the point and partake for the advantages that it gives.
2. Without rulers, their neighborhoods would likely become ganglands/feudal systems pretty quickly. -But the war on drugs would be gone and nothing would be "illegal," (that doesn't mean what you think it means) so they wouldn't have the incentives they do now to perpetuate the violence & stupidity. It won't be as bloody as it is today after the initial shock wears down.
3. Others outside their community would likely pay for private security firms to protect their clients from the hostiles in such communities. Those private firms would do their own cost/risk analysis to determine if they should build walls around to contain or go in and take out troublesome leaders or whatever other solutions they can find.
4. Eventually, these ppl will step in line because they like to eat and trade with the outside world. They'll integrate so much faster without government keeping them divided that it'll seem like a miracle.
