My problem with preppers is the over estimating on whether they’ll be in a position that these skills will have any effect, and the under valuing on steps we could just take to not have this future in the first place.
Like, you’ll need a farm right off the bat, or your first steps in any guider are how to violently take somebody else’s land. Followed by step two, keeping that land from other humans who don’t want to die.
Instead of prepping, become nomadic scroungers or live in a fricking farming commune in the first place. Basically descend a couple levels of societal development and you’ll already be self sufficient and ready. Like the Amish.
Or, you know, voting for politicians who listen to scientists.
Anything beyond being self sufficient for a month is overkill in my opinion.
Doesn’t help that dod pentagon is so big because the USD is so strong. Kinda bad for national defense if the dollar loses value.
