People's use of cash would depend on how much faith they had that its value would be retained, wouldn't it? So it would probably depend on the exact situation.No it wouldn't, if the infrastructure crashes on this sort of scale your cash is worthless as everything else follows. Assuming you had more than £50 in cash anyway since you can't get any more, what good is that to a shop that can't access their account to credit or withdraw cash? That can't pay their staff, that can't pay their suppliers? Never mind impacts further up the supply chain.
If there were some kind of infrastructure disaster but I hoped that the system would be restored in a few days/weeks, and I owned a shop full of stuff, I'd probably accept cash in exchange for what I had there, at least for perishable stuff - what would my alternatives be?
