Fair enough. But if the grid goes down, no one in today's society values gold. No one will take gold, it would be a barter system until electricity was restored. Even after a golbal EMP strike, it would only take a few years to set up another global internet, then Bitcoin would be king from then on in society. Even if the government issued a digital dollar, Bitcoin would reign because there is no way to completlly control it, baring quantum hacking (but that's another conversation). I think having food and supplies on hand to last 3-5 years, while also hodling crypto, for when it becomes a predominent way of regular people to conduct business without money processors getting involved. But who knows? God only know's what the next 20 years is going to look like.
