Paying cash for everything you still can is even better – because if enough of us refuse to pay otherwise, it will be difficult for not-nice people to impose something awful on us. That being, of course, the elimination of cash – which entails something far worse than paying for things digitally (as in Central Bank Digital Currency, or CBDC).

It ought to be obvious what "digital" money will allow. Just the right word – and in italics for just that reason. You will be allowed to buy what those who control your money decide to allow you to buy. They will have the power to do this by dint of knowing what you're trying to buy.

They will also know how much money you have – and where it all came from, down to the last cent.
