Whether you are looking to create a self reliant homestead, a survival retreat or a go totally off grid you need to recognize the immalleable fact that as I always say, "Survival is a team sport". No matter how resourceful, skilled, creative or downright awesome that you are, you will always do better; live better, be happier, have more, be more satisfied when you are part of a quality community.
You should always maintain your individuality and self sufficiency (sovereignty) but when you pool and share your resources you will be better off. Never allow yourself to "relax" and stop learning, honing your own skills or being productive. The key is creating a community based upon people standing shoulder to shoulder not in a line or carrying some. We are not talking about communal or socialized community where people are all treated equally no matter what their productivity or effort. The point is to educate you about people, how they think, how they are motivated, physiology, psychology and sociology. Learn how to construct a viable social order that assures the survival of all.
The paradox in the creation of community (society) is that the more efficient that it becomes the larger it grows expanding and strengthening itself with the addition of each member. Unfortunately, at some point the mass allows some people to become non-productive and diminish instead of better the whole. The problem is complex; people have grappled with it for centuries since the idea of self governance and personal rights emerged.
