"“Cash is contraband, but people have got cash,” the former prisoner explained, “but it is not cash like cash in hand. It is untraceable. It is all based on numbers. People pay each other with dots.”"
Economies and mediums of exchange will find a way where they are needed.

places that do a lot of cash business will naturally continue to accept cash as long as it exists. several business I patronize only accept cash. it's not some colossal injustice if the fancy coffee shop is plastic-only.
But to be clear, I never once suggested abolishing cash. And I'm not suggesting that now. I'm saying that cash continues to exist, we allow businesses that want to go card-only to do so, but make sure that everyone can easily get a card.
cash is concrete. People can count how much they have. They know how much they spend. They can give it to someone in the middle of nowhere away from computers. If we had cards, all kinds of tracking and tracing would be added. Civil forfeiture could happen while the cash card was in your pocket.
There is just so much society would lose for the business convenience you're asking for.
