The issue is with fintechs that are not really banks, so they keep your money in a "program bank" where you are not the direct customer. You can't go to the program bank and say Fintech XYZ went belly up and I want my money, because you are not the banks direct customer (even though in some cases your name is legally on the account for FDIC insurance reasons).
Open banking tech is way more about the former than the latter.
A sizable fraction of what bank employees do involves error conditions and fraud. The happy path has been automated for decades. One of the big discoveries when PayPal started up was that they were not in the money transfer business. They were in the fraud prevention business.
