Cash is not resilient in some pretty important ways: It is vulnerable to counterfeiting which mean citizens lose out regularly as they don't have the means to check all cash is valid as shops or banks do. Physically it is vulnerable to destruction and cannot be replaced if burned for example, unlike a bank card or other token of identity linking you to your funds. It is vulnerable to devaluation (in has this in common with electronic cash) In the event of societal collapse or degradation it becomes worthless fairly quickly, which is the opposite of resilient. Cash is not at all resilient compared to electronic money therefore, and people are voting with their feet to get rid of it, laws like this will just delay the inevitable for a decade or so. Bank cards will also disappear pretty quickly IMO (next couple of decades), as they're just a physical token of ownership and not really required if you can rely on say a combination of biometrics to assert identity.
