I have serious doubt as to the plausibility of this idea.

Anarchy, as a philosophical concept, is an interesting abstract to argue. However ... there is an entire movement of people who are honestly searching for this sort of reality.

Outside of the argument of the beneficial/detrimental value of anarchy, there is this plausibility question. Can people really have no structure, no leaders? Sure ... I can buy that thre can be a lack of real government (hell ... look at many African nations, such as Somalia), but there is a real sociological finding that people naturally seek leaders.

Even looking at the anarchist movement, this is seen. For a movement to exist, there must be one or more motivators or leaders. It seems that even within those people most vehemently buying into anarchy, they cannot realize their ideals.
