I wish you well on your move away from society and off-grid. I can understand all tour concerns. My family moved to a rural area about 15 years ago and built a liveable shed, with a small solar system, had chickens for eggs and meat, tank water, etc. to get away from some of the type of things you mention.
After all children moved out and due to some health problems we have since moved back to a rural town, but we learned a lot from the experience and still conserve water, recycle and reuse as much as possible etc. and still grow veggies and have chickens.
