If there is a major grid down scenario, cash and bullion are the least of anyone's worries. And would only help those who have it on-hand. But with solar chargers and generators, bitcoin can still be transacted between individuals who hold their keys if needed. But again, that will also be the least worry. No power, no running water, no fuel, no food deliveries, no grocery stores, no heat or A/C, etc.
So then available cash and precious metals will be worth more and electronic dependent technologies go the way of the dinosaur.

Things that have inherent value will never go the way of the dinosaur.
