What a CASHLESS society REALLY means
(links.hackliberty.org)
Privacy is the ability for an individual or group to seclude themselves or information about themselves, and thereby express themselves selectively.
I'm sure someone, somewhere is. The bigger problem is that society seems to be moving in that direction without first having a serious debate about whether it's a good idea.
I take a hard line and hold the position that, if you're in business, you should be required to accept legal tender (maybe only up to a threshold where Know Your Customer laws kick in). There's a strong social value in there being spaces for unmonitored transactions.
