When that is the case you can use electronic payment. But they are not mutually exclusive. Electronic payment can coexist with cash. The fact that electronic transfers are convenient for large purchases does not negate the convenience of cash for small person to person transactions.
People are making the argument that because electronic payment is convenient for large transactions, therefore cash is inconvenient in all cases. This is a falsehood. They are both convenient in different cases.
In a way, convenience is in the eye of the bearer.
To me, it's much more convenient to have transactions over and done with by the time I leave the store, rather than ending up with an unauditable monthly statement that could have extra or missing charges.
(Never mind the whole commercial surveillance angle. I've actually made it a point to go back to cash at various places I'd gotten lazy with. Hitting the ATM every week is a small price for participating in society's most popular mix network)
Cash is inconvenient for small purchases. I hate dealing with coins. I wish they would finally kill the 1 and 2 (and maybe even 5) cent coins in the Eurozone.
