I don't know that it has, I just want to be clear that efficiency isn't a good enough reason to force compliance to a proposed 'system'.
People seem to want to cast libertarians as radicals or extremists, and I've always seen us as the opposite. We're the moderating force in most circumstances, often the only people asking 'Do we really need to get the police involved?" when it comes to solving our problems as a society. We believe voluntary cooperation is preferable to coercive mandates. If there's not a damned good reason, no one should take up arms against their neighbor for their own convenience.
Lets take your scenario and use it this way then; OK lets say the community is made up of many diverse people and cultures living within said community. Now the next thing that happens is a trend gets to going in and amongst the community, and that trend is to join a gang maybe. Then next the gang begins controlling and doing bad things all throughout the community, and people become helpless to stop them. Alright then next someone says in a community meeting that is formed once people have had enough, where as a man stands up and say's "hey lets bring in the police and/or the FBI to stop this mess", but quickly another one says, "you mean to tell me you are willing to give up your freedom to the police and/or the government in order to take care of this problem" ? So the person sits back down and thinks to himself that there is no hope then, yet meanwhile the one that challenged his idea to get the police involved or the FBI involved, was unbeknownst to him a man that is living secure and not at all afflicted by the gang's that have taken the area over, and this in as much as say others are, so why would he care as long as his turf was being protected, and him and his family is safe, yet others suffer around him greatly as a result of his inaction found in it all ?
Now who would represent the gang, and who would represent the people in many other scenario's/parable's that may match this one in which is now given maybe? Think about it....
