>The obvious first casualty of any apocalyptic event would be electricity.
Which is why I said it'd be useless in the event of war. The deepstate's plan clearly assumes worst case scenario (they assume they will lose - which is why they have all those deep underground bunkers. They trigger war then run away like a bunch of pussies).
I've slowly navigated countries towards protecting electrical systems (see the SHIELD act, and cyber security utilities provisions):

If you're already on renewable energy then you're largely immune (just needs circuit breakers and a good sense of timing).
>Food supplies - limited to what you can carry and protect
You're assuming bugout scenario. If you're in a nuclear scenario, you won't be travelling anywhere without a radiation suit. Bugout is only viable during authoritarian crisis, which implies power is functioning.
>Bartering - What do you have that is "valuable" to someone else.
Knowledge. A shit ton of it. Doesn't weigh anything to carry, and you can't steal it from me. If you have skills or craftsmanship, you'll be in demand. I also have a harddrive with the entire contents of Wikipedia stored on it, as well.
Item wise? Well, if you kept that food supply I was referring to earlier…
But that said, valuable to who? Everyone has different needs.
Shortstop:
1) If the main currency is dead, you're either going to see crypto or bartering as stand-in (likely both).
2) If you're at N-day war, ANY currency is going to be useless (you either can't trade and have to hunker down - food supplies, or if the radiation isn't so bad you can walk and talk, your JIT infrastructure is going to be so badly disrupted that no-one is going to want gold and everyone will be haggling for clean food and water. You can generate the latter with a variety of techniques. Growing the former in a warlike scenario might not be possible).
>Essential material goods become the new "currency" via the original barter system.
I'd imagine, specifically, seeds (or salt, like the Romans used, given it was a preservative).
The issue with knowing what system to gear towards depends on what last ditch plan the deepstate execute. If we can neutralise them before they trigger N-day (which I'm thinking is their failsafe depopulation angle), then we can have a new currency or crypto.
But if they do go N-day, then the extent of the damage dictates what we can use.
Securing America's nuclear reactors against EMP would be a HUGE step (because if the nuclear reactors go critical then it worsens). Just so you guys can see how badly designed the US electrical grid is: some nuclear reactors rely on other nuclear plants to supply power in order to shutdown as their 'backup generator'.
(It can take 3 days to fully shutdown a plant.)
