The thing that isn't clear in this article is, the particular type of anarchy.

There is natural anarchy, where nature is the organizer of life, and people are free. Often this is called anarchy.

Then there is Government anarchy, where nature is partially displaced by Government. What this does is to allow Government people freedom - as nature would have it anyway - while often totally removing freedom from those who are under the thumb of free Government people - totally against the way nature would have it.
