Ultimately they're very different businesses. Card payments and banking are related but not directly. The truth is that all I know from Stripe about the card networks, card risk, etc, has proven not useful in commercial banking. I couldn't even use their IP if I wanted to (!) and they know that as well as I do. If I started a payments processor I'd be in deep trouble. But a different part of finance, with a different business model...no one seems that worried.
