You are aware that many places don't accept cash, right?
I don't know about other countries, but in Poland you must accept cash except for a few cases (over internet, large transactions, places without employees).
Well its about time (a decade ago) to ignore those places and be vocal about it.
Contactless is all fine and dandy but straight out refusal to handle cash is a big negative for the users, which is the only perspective anybody cares about. On top of obvious long term massive loss for society and personal freedom. Don't feed the actors that are harming you / us.
Most EU countries require cash acceptance. There is also an EU-wide legislation in the works: https://www.europarl.europa.eu/legislative-train/theme-an-ec...
