seems to imagine that there's a magical force surrounding supermarkets meaning they'll always be open and well stocked, that theyll always be able to go to one, and that there'll always be someone else able to go for you.
Well if food becomes unobtainable, I'm not planning to board up my windows & hide my food & family in my basement. The magical force of prepping won't protect us from civil unrest & looters.
Very few people can prepare for the sort of scenario you describe.
Many people, due to financial hardship, cannot prepare at all, or can prepare only minimally for any sort of shortages.
However, as many posters have tried to explain over and over again, there are many, many, many more people who, during times when the JIT delivery system has been working efficiently, have had the wherewithal to prepare in a sensible, gradual and calm way for times when that delivery system will not be working efficiently. Some of those people have taken the opportunity to do so and, when those delivery systems fall down, those people will be the ones reducing the demand on a limited supply of goods - to the benefit of the people who did not have the means to buy anything in advance.
Many people had the means to prepare but didn’t. Fine. Your choice. Except actually not fine if you’re in the shops during the shortages taking a bag of pasta or flour that could have gone to someone who had no choice but to wait to buy it.
People keep banging on about community spirit and helping each other out and ‘my neighbours will happily pick up shopping for me’. Great, that’s wonderful. So nice that people help each other out. You can do both you know? You could have built up an essentials cupboard and still ask for help if needed. You just wouldn’t have to ask for quite as much help, which will reduce the stress on your neighbours and enable them to spend more time and energy helping people who simply couldn’t do anything in advance.
The idea that there’s no point in taking sensible, gradual measures to ensure you have an extra few weeks worth of essentials is pointless because it won’t help you if society breaks down to such an extent that there’s looting of private homes is just ridiculous. It’s like saying ‘it looks like rain but I won’t bother to take an umbrella because if we end up with a force ten storm that umbrella won’t do me any good.’
