I don't know anyone who thinks chickens are the path to complete freedom from society. I do know many who feel that chickens and other such measures provide a level of independence from societal structures they wish not to associate with or do not trust.

Having your own infra is similar. You still need electricity, replacement components and perhaps friends with similar ideas that you can trade information/services with over packet radio links but it is certainly better than whoops, no internet for a few days, nothing works, touch grass.

It also is a nice backup in case anyone starts actively censoring (versus the passive self-censoring created by tempting people into walled gardens) the internet where I live. Being able to shitpost over encrypted packet radio and exchange files/news is certainly better than radio silence and state media.
