They have dealt with the ecentricities of their local money their entire life. Bitcoin is new. In the end, from an objective standpoint, scanning a QR code and confirming the transaction is easier than dealing with debit / credit cards -> bank accounts -> checkbooks, etc. I still have a POS time with routing numbers and bank account numbers and those are effectively fiat bitcoin addresses.
Bitcoin is so much easier to use because all you need to use it is a bitcoin address.
