>but its likely that you will be able to use it for payment even if all else fails.

Can you give an example of a modern economy collapsing and reverting to gold as a medium of exchange?

In the event of a societal collapse so great that no money is usable, it's pretty hard to imagine people caring about Bitcoin. There might not even be power in this weird Mad Max scenario. They'd probably want to barter for goods.

So you think when society around you is failing you'll still have enough infrastructure to be able to do transactions in bitcoin? Seems like a narrow scenario. Bad enough that there are no reasonably stable fiat currencies to be able to trade (whatever they may be because my value is in companies not currency so I can use whichever) and yet good enough there is still a working internet and enough miners for the blockchain to work.
