If there is any doubt that people would start getting locked out just look at politics and de-platforming today. Once everyone's money is in a central location and people are on the "wrong side of the fence" they would be put on financial lock-down and it might not even be from their own government or for a legit reason. Without access to their money hiring lawyers would be a challenge.
…but people do not want to be locked out of their money."
I'd like to think cash is not going away but I'm not at all sure that it won't disappear, I reckon its life is in the balance.
I make a point of using cash whenever possible to the extent that I'll withdraw cash from an auto-teller before I go, say, to a supermarket where I'll pay cash. It's my small way of bucking the trend to e-cash.
I find it alarming that so many people are just prepared to pay with their smartphones and do so without a second thought. It's clear to me these people have little concern about being 'locked out of their money'.
Even when e-transactions fail through the network being down these people aren't deterred, they expect merchants to give them credit. Recently, the e-terminal at my local coffee shop was down [I pay cash] and the proprietor told me that he had to credit all his e-customers because they didn't have any cash and it turned out that many never repaid him. Not only that but he actually lost some customers—rather than repay the debt they went elsewhere (there are about a half dozen similar shops near by).
BTW, that e-outage was a big one and was well publicized but even then it seems few bothered to take cash as a precaution.
Unfortunately, I don't see the decline in cash contining unless there's widespread disruption to the banking system and banks start failing as they did in the 1930s. Nevertheless, I hope I'm wrong.
