Yes and no..
I think being prepared is important for just in case... But do I stash hoards of food and other stuff, not so much. Maybe a 4 to 6 day supply. But, I guess thats me. Alot of people, and I mean a metric crap ton of people, I know don't have the common sense the man gave a rock, they can't, lets say grow corn, or some beans or even find the eye on a potato to grow it, they can't identify a walnut from a hickory nut from a chestnut, or gut a deer, sheep, cow, pig or even deal with a chicken, fish or squirrel. They wouldn't know poison ivy if it were swiped through their butt crack like a credit card, yet alot of these same people claim to be preppers cause of their hoard. These same people are truly inept at mechanical devices, know nothing of electrical, can barely change their own oil in their car or a spark plug in their mower, if it weren't for You-Tube or the interweb they would be helpless.
I hope growing up in a very rural area, I've learned to do quite a bit with very little, the hillbilly ingenuity factor, I guess you could call it. Farming, ok, lets do it, what are we planting, growing, havesting, butchering, or rip any engine down, a 2 stroke chainsaw to an 21 liter Caterpillar, split a tractor in half, drive and operate or use a dozer, excavator, pan or trash truck. Wire up a house or genset, fix a genset, hotwire a car or semi, or heck just get them to run if you have the key and it won't start, use a welder or torch. On the same token above, I know people you give them a rusty junk pile, they will have a MadMax dragcar built in 2 days.
I think it's not just about ones food and ammo stash, it's about having the knowledge, skills, life experiences and basic common sense to do other things, get mobile by any means necessary, fix, repair and skirt by off of nothing and or making it off of very little.
