Some prepping appears to assume a baseline for longevity of scarcity and disruption.
"A Canticle for Liebowitz" illustrates how a very long baseline still brings one back to starting points, given the fullness of time (many centuries in this case).
For practical purposes, I propose that prepping needs to assume a return to pre-industrial life for the duration of any prepper's lifetime. IOWs, the baseline of scarcity and disruption might well be generational. Not just a rough patch in the lives of people prepping today.
Already we are, for all practical purposes, reverting to a form of feudalism. Perhaps another Dark Age as well.
Yes, stock our abbeys well. And play the long game.
