And this is what bitcoiners and similar don't understand. It's not like your internet connection will remain happy and stable while the rest of the world goes to hell around us. Telecomms will be a first-class target, and most systems have some pretty central points of failure that would make juicy (and easy) targets.
In such a situation, if you've chosen to use an electronic cryptocurrency dependent on things like robust network and electrical infrastructure to function as your primary value store, you're going to have a bad time.
This doesn't even contemplate the additional issue for bitcoin and its derivatives: the blockchain depends on a consistent, global view of network transactions, and apocalyptic-type network segmentation will cause severe forking in the blockchain, further diminishing the utility and therefore the value of the [already worthless] cryptocoins.
