Anarchism means 'without rulers' not 'without rules'. If you really want to grade licenses on how anarchist they are, the GPL is obviously more conducive to a world without rulers than BSD-style licenses.
For a semi anarchist society on a large scale, check out Catalonia during the Spanish Civil War. This was anarchism in the original sense of the word though, and not in the recent US sense of the word (US liberterians/anarcho-capitalists seems to long for a return to something akin to feudalism rather than freedom in my opinion).
