Not sure it's possible to create a stable oasis of simplicity. The world we today inhabit, with advanced divisions of labor, technological-dependency, and social interdependencies can't just be easily disentangled. Even self-sufficiency is an illusion.

Unless you're literally living off the land through hunting and foraging, with no dependency on technological civilization or social society, any claims of self-sufficiency are pretty suspect.

Even this conversation we're having right now, over the internet, is contingent on social order. It is contingent on the telecommunications companies that continuously maintain, expand and support that communication. While it doesn't require explicit cooperation between you and them, because of the market mechanism, I completely disagree with the argument that the market mechanism makes you self-sufficient. Capitalism and free exchange doesn't remove the dependency -- it governs the interaction. This claim of self-sufficiency within a market, is one of the most problematic epistemic claims a lot of libertarians and anarcho-capitalists make.
