I wouldn't say big, most people don't have cash on them. But indeed, there is still a small part of commerce which prefers cash. If you go to small street shops, they will often ask you to pay in cash. If you don't have cash, you can make a direct bank transfer to their bank account. However, if you pay by card, they will charge you a premium—two reasons: avoiding card fees, but also, a socially accepted form of tax evasion. The government knows that lots of little shops barely survive, so they don't really crack down on this.

But a gradual shift to CBDCs and the natural death of senior citizens preferring cash will eventually move us away from the anonymity of a society that embraces cash.
