Really? This would be devastating? We can't live without electricity, electronics, water pumps?
Can you farm without electricity? Gasoline? Do you have all the pre-electricity farm equipment that would allow you to grow food without a tractor, power tools, etc? Does your well pump even work without electricity? I'll bet it doesn't. I'll bet you can't really live off the grid unless you're Amish or Mennonite. You simply don't have the pre-industrial technology to get along in such a world.
Many in cities and suburbs, after 3 or 4 weeks, would wind up going out into the country to forage if they could find gasoline to pump (and gas pumps work with electricity!), because the supermarkets would be empty and all the food in the refrigerators/freezers would have spoiled after only a few days.
To your "off the grid" house. Probably.
inb4 "I have an arsenal of arms to keep them away"
Your best defense and survival depends on your neighbors. Because one lone person with a stash of food and arms can be out-sieged by the outside world.
I would suggest watching "The Trigger Effect," Episode 1 of James Burke's "Connections" series. Anyone (sensible) who watches that and looks around at the technology that supports all of us will come away with the conclusion that if it seriously went away for a month, we'd be fucked. The shit would so seriously hit the fan that your incredulousness indicates you are either completely out of touch with society at large, deliberately myopic, or some teenager that hasn't lived life enough to have any kind of broad view. Good luck with that.
