Only in cataclysmic scenarios? I'm sorry to inform you, but in such scenarios most probably cryptos won't work either, as they all depend on proper working of the internet.

It doesn't even need to be a Madmax situation: just imagine a war between the US and China, with one of the involved causing an prolonged interruption in the communications between the two countries, as they have significant numbers of nodes/miners in most blockchains.

I'm afraid blockchains actually depend on the normal functioning of society with all its governmental structures in more ways than most crypto enthusiasts are ready to admit.

Yea my wording might not have been on point.

I was thinking of an economic or political collapse where technology otherwise remains more or less intact.

Anyway, we agree that it’s a niche scenario.

The US and Canada could block each other and it wouldn't affect Ethereum at all. Everyone in the world including those two countries could still use it.
