Idea of off griding, is opting out of everything.
I think that's inhumane, what you rather want to, is have:
1. Your own grid (mostly as a backup)
2. Local grid (community)
3. "Offshore" grids. (National (state) as well as international - one step at a time)
Remember
Lone wolf dies, the pack survives.
Sovereignty is not about going in the woods and dieing alone, its about optionailty.
Creating resources that you can rely on if the time comes, only when the time comes.
Humans alone as individuals are nothing, its how we coordinate is, what makes us stronger.
Sovereignty is about acquiring the strength to quit toxic relationships and bravery to create new ones.
