I would add to this that covid did cause a major resurgence in a different flavor of prepper: "back to the earth" people who strive to, among other things, produce more of their own food (be it growing produce, raising livestock, or even doing more cooking and baking using raw ingredients rather than relying on premade food). Interest in gardening, homesteading, baking, and learning to live off the land skyrocketed during peak covid. Sure a lot of that interest has subsided, but much like how the great depression permanently changed the attitudes of people who lived through it in regards to reusing things instead of tossing and replacing, the experience of scarcity and uncertainty regarding basic goods (for most first-world folks, for the first time in their lives) made a permanent mark on at least some of the population. And this is a much more practical type of prepping, because instead of coming from a fantasy of what disaster might befall the world, it was a direct response to a disaster that actually happened.
