I think that's an important distinction to make between such a place, and a place of anarchy or a commune, which aren't necessarily places that don't have "rule of law" and aren't necessarily hubs of raw violent chaos.

Not aware of any anarchists that want whatever a "vacuum of justice" is.
In fact, note that the concept of a jury is intended to work this way (although is missing many elements, and exists under the permanent organisation of the court) - a temporary organisation gathering to find justice, then dispersing.
Unfortunately it's difficult to tell the exact outcome of implementing any of it on a wider scale, as the times leftism has actually been in power have largely been during times of war where a lot of theory was thrown out the window, or using leftist messaging to implement something closer to a dictatorship. All we know is that a lot of it works when implemented in our own communities.
Is this a good faith interpretation of what you honestly think they were saying?
