That's literally exactly what I wrote in my comment.

So how does it work now with bank fraud or technical issues? Ignore the fintech layer for a moment, just consider a bank like Chase or Wells Fargo. If their mobile app causes an erroneous transfer, or the backend removes money from your account or maybe doesn't give you the expected interest amount your saving account due to a bug ... what is the recourse? For a reputable company, even if their support is a hassle, they'll probably make you whole eventually. But presume they don't address the issue or repeatedly have widespread issues, what then? Do banking regulators step in? Does the public just need to rely on torts and threat of a suit or bad press?
