True (perhaps) IF they already have an ass-load of PM and no crypto (and some basic computer skilz.)

False (perhaps) IF they have have an ass-load of crypto and no PM.

Perhaps you would not have so many failures if you recognized some of the nuances of strategy.  Different people have different situations and there is no way to accurately predict the future.

BTW, it's a fair bet that free internetworking via corporate controlled global packet transmission infrastructure will fail (in one way or another) long before we hit rock bottom in a real SHTF scenario.  (By 'free' I mean free of various kinds of controls of course.)  Not that certain varieties of crypto won't be able to work in such an environment to a degree, but they won't work well for even the more technologically capable and likely not at all for the rest.  A dusty old wallet might be worth a fortune on the other side of such an event, but one needs to stay alive long enough to get there.
