Well these questions are mostly for people to LARP about how tough and self-sufficient they are. No, society wouldn’t collapse because we didn’t have electricity for 99% of our time on Earth. Electricity was a luxury as recently as 100 years ago.
Number one issue is, can electronics be fixed? If yes, temporary issue. If not, and we are literally without power (for some magical reason) we just need a million more horses to cart food around. There wouldn’t be much looting. The new iPhone won’t work and how are you going to get away with anything bigger? Guns and locks still work without electricity.
I personally would start buying up property from people ignorantly fleeing cities. Most major cities are built on great harbors or waterways for sail and steam ships. People will try to farm, fail at it, and just buy from farmers like before. Food will move by boat first to major ports. Every prepper in the middle of nowhere will sit in a bunker eating canned vegetables while the rest of the world goes on with their lives.
You don’t actually need Facebook and Tik Tok. You won’t die without it. You’ll just read the same gossip in a magazine.
