Anarchy isn’t a specific form of rulership. Neither is it chaos. It’s what society defaults to in the absence of rulership. Delete our social programming and millions of years of evolution kick in. We default to what best maintains social cohesion.
Likewise occupancy & use isn’t a specific form of property. It’s the absence of property. Neither is it chaos. It’s what society defaults to in the absence of notions of entitlement, rights, and ownership.
Anarchy and occupancy & use are mutually dependent concepts, two sides of the same coin.
