Very true. There's a small segment in the netherlands who are doing just that, with the slogan "betaal bewust contant" (~pay cash consciously/purposefully), e.g. they go out of their way to pay cash at supermarkets even when there is only 1 cash register that allows it and all others are cashless. As I understand a similar movement exists in germany and is much more popular there (I guess due to their history with totalitarianism and persecution).
