if its at the point where you need "some land i can build defenses on" that's a time where you can take what you need anyways. when i was a teen i was super into that kind of survivalist mindset. that's not going to happen. its a fantasy. gold and silver are far from valueless rocks. i have family members that bought 10 yrs of food and a bunch of other survival crap (hurr durr you cant eat rocks anon!) while i bought assets and my life is much better off than them. all that survival shit is just rotting in a garage. be diversified between gold, silver and crypto. get into realestate if you can. don't plan on sticking around in the west your whole life.
