I don't think this analysis is good. Poland has many, many banks. Maybe not 1000s, but not 10. Essentially every bigger neighborhood may have a local bank, which are like Credit Unions in the US--less popular, but also used by quite a bit of people. The key is that all these banks use simple unified system which has to be agreed on. And sending money to people is very simple, mostly based on the fact of knowing other person's bank account number, which is IBAN, but without country code. In the US sending money from BoA online to a person you're not affiliated with: good luck.
