VAT evasion is widespread in certain countries (like Italy for instance), and pushing people to prefer electronic payments to cash is empirically the only realistic way to counter it, but there will always be resistance from small retailers until payment fees are low enough. The availability of electronic payments should be universal, I personally hate being forced to constantly carry cash on myself at all times.

In a cashless society, there's no point in mugging and robbing, because people don't have untraceable items of value on the at all times.
