Of course it does. But so did society that started adopting the telephone, or automobiles, for people who didn't have money to buy telephones or cars, or didn't want to get on board the technological change. And what doesn't discriminate against poor people, by the way? The poor are always getting the short end of the stick. You come up with ways to help them, but railing against a new technology because it disadvantages some has never worked.
I'm not saying I'm in favor of cashless, but whatever the technology is, life adopts it and moves on. People have to deal. Or they die and get replaced with people who do. You will never get 100.000% of the people on something that takes away what you used to rely on.
