I’ve recently given this a little bit of thought – having moved into a Proper House I now have room for supply storage. Read a couple of books that my ever-helpful mother-in-law (really) picked up for me from the charity shop.
In the end I decided I would ‘prepare’ for a minor stumble of civilisation e.g. something that led to a few weeks of fuel/power/food shortages. But the actual collapse? Really couldn’t see the point of investing that much time, money and effort to the point of actually being able to ride out a situation that civilisation isn’t coming back from.
The sheer quantity of food required – mostly in the form of long-lasting dull filler – to last the recommended year ‘self-sufficient’ before you can hope to be growing your own is nuts, plus because you have to rotate your stores and eat the old stuff before it expires means you’re locking yourself in to eating rice and beans for the rest of your life. And you aren’t going to be able to learn and prepare growing your own post-apocalypse so you have to start now. Plus you have to work out how you’re going to defend it from everyone else who will want it. It just puts you in a horrible mental state – paranoid, defensive, cynical – and you can tell quite a few intensive preppers actually *want* disaster to strike to validate their lifestyles.
More fundamentally, what would be the point? To live on in a desperate hunter-gatherer/subsistence-farming lifestyle just to continue existing? A real global disaster would be utterly miserable – hiding in your cabin in the woods hoping the bandits don’t find you, no idea what’s going on, wondering whether that cloud on the horizon is radioactive, if the cut you just gave yourself trying to butcher someone’s feral pet is going to turn septic and kill you because there’s no antibiotics any more? No thanks…
