Liberartarians can only exist within a conventional society
A society based on liberatarianism will naturally collapse
I proppose this post as the hand waving of the day.
There is an profound mathematical analogy I could present to illustrate my original criticism.
For a flavour of this refer to Langron's Lambda parameter in the study cellular automata.
The most productive societies occur at the boundary between authoritarian and anarchy.
A society based on pure liberartarianism will inevitably collapse through decadence.
Human behaviour is not subject to pure mathematics. In addition, no such societies have hardly existed including anarchy.
