It's because .22LR isn't a serious survival round, at least not by itself. Fine for rabbits and other small game but you're gonna need something a bit heavier for bigger game, including marauding humans showing up from time to time to kill you and take your stuff. .223 is ok especially if you have some steel core to help punch through lightweight armor, but you really ought to have something that can reach out and touch someone. 7mm Rem Mag shoots flat but it's not popular enough to have a lot of options. Think on it a while, see what the experts say.

Don't forget a handgun for close-in work too. .45 is a perennial favorite but .40 S&W packs a great punch (far better than 9mm) and almost anyone can shoot it since it has a nice short casing meaning grips that are easier for a wider variety of people to hang on to.

Plus... Gold? That's for amateurs. What you really need is a dozen or more miles of copper wire in various gauges. The guy who can wind generators and electric motors is going to be able to set his own price when combining efforts with other enclaves.
