Personally I'm not an end of the worlder.
If the social chaos scenario happens, you are living in the sticks, and you run out of say-auto gas you are hooped too....Or seeds for your garden..or ass wipe...or coffee....penicillin.. How much of this stuff do you store?
I couldn't live in this climate without electricity or ng. Need the grids here.
I did it for a couple years as a kid in the rain forest, more of a lark then. Still used the grocery store and liquor store.
In this province we are only a generation away from people who have lived self sufficiently, off the grids, and none of them want to go back to that. Those skills are pretty well lost.
