Laudable though going cashless is, there needs to be a number of caveats attached. The cashless society in Sweden comes at the expense of anyone from outside Sweden not being able to access a large number of these services. In the Netherlands, there are shops that only accept Maestro cards - that’s it. No cash, no credit cards, no other debit cards, only their own local cards. It’s the same with the ir national transport smartcard - the OV Chipkaart - you can’t get one unless you have a Dutch bank account, and you can’t get a (proper) Dutch bank account unless you have a Dutch address.
Think also of numerous countries that do not really “do” cards, or accept only local ones.
I honestly can’t believe people whining about “how dirty” cash is. They’re the kind of people who “don’t do public transport” and who presumably float through mid air and pick things up with a grabber when they go shopping (and wipe everything down with wet wipes when they get the shopping home)
