I've watched a lot of off-grid people. It's laughable. Do you know how much technology they use? Camp stoves. Tools operated by batteries, etc. They can only live off-grid by taking advantage of of tech.
I was born and bred in Africa. Believe me, that's where people really live off grid.
Besides that, there is nothing that prevents these off-grid communities from being destroyed by sudden tornadoes, floods or fires.
And, no, it's not the same thing.
I've written hundreds of articles aobut this, explaining this. It would take me too much time to go back and find the one that explains the concept exactly. However, here are a handful of articles that touch on it. You're welcome to scroll through all my articles.
