This is same that i meant myself. Local gang so established, it is seen as a government itself, runs the place and national laws do not apply, resulting properties being from perspective of law, illegal - can't be officially sold or mortgaged, have no title deeds, and would have been razed if government had access there, except if a city official with a bulldozer appears, the local gang will meet them with machetes and pitchforks, and sending in tanks and helicopters is not worth it. It's not "deregulation", it's "lawlessness".
