I have seen two of these now. Stores that claim not to accept cash for goods.
Cash is great. I don't want banks collecting and selling my analytics. I don't want my card to get swiped by dodgy machines. Crypto is alright but I assume the public ledger makes it easily possible to analyse purchase history and correlate likely identities unless protective measures are taken.
On the plus side, anti discrimination legislation in Philadelphia, New Jersey and New York (proposed iirc) has banned such stores, so they won't become impossible to avoid there.
