I think that's a bit harsh. Past generations thought of these things and incorporated solutions into their lives that today would be called emergency preparedness. The silent and great generations did just dandy off-grid for years at a time very far from towns. Manual saws, axes, machetes, rope can get a lot done and keep someone strong.
There are some nutty preppers, some fear-porn youtuber preppers that scare people into buying things but then there are the rest of us that just accept things can go sideways. Anyone that has been watching fringe less-than-censored media have seen the massive fleets moving towards Iran. It's about to get real and when it gets real then it's too late to incorporate most off-grid solutions. I think it's great they are at least asking questions and thinking about options.
