No, I am suggesting that in a worst case scenario, an emergency fund full of cash is useless (on a multiple year timescale, of course how many years is subjective).

It’s conceivable to imagine a scenario where resources are so limited that acquiring them becomes a do or die situation, which is what I imagine the previous poster meant by “zombie apocalypse” scenario (or more realistically, war). Or I erroneously assumed “zombie apocalypse” to mean worst case scenario.

I also forgot to include a less drastic measures of also owning assets in a different country and the rights to live there in case you need to immigrate.
