Thinking on both your comments in this thread. In the first one, you are quite right. Cultural norms vary from place to place. I believe it is Italy where they don't have a concept of queuing, it's pretty much a free for all. In airports it's likely staff won't intervene as they would fear being called out for racism (or culturalism if that's a thing) if they told someone not to queue jump.
I also totally agree that smaller communities is probably the only way anarchy can really work properly. The bigger a community gets the more disagreements you're going to get and that will then start calling for some sort of authority again.
In my experience, pretty much all of mainland Europe hasa different sense of queues compared to Anglo countries. But that if course is a vague generalisation...
In the larger community, power centres (due to central authorities) begin forming. These will again start to try and impose their will. Coordination of Individualists and anarchy is like herding cats...
