So, only an agrarian, matrilinear society is truly free?
You have a very limited world-view.
As I explained already: an anarchical
community is not a
society. A society is a collectivistic, state (mafia) based organisation (patriarchy). Most of history, the nonpatriarchal, matrilineal communities were not agrarian, but hunters and gatherers. The stockbreeding and animal husbandry was followed by human breeding and human husbandry: unnatural, perverted, monogamous pairing families and harem families, constructed for the purpose of submission and taxation by organised violence.
