If you think about running your own bank, guess what, the entire business model is inherently fragile. The payment services banks offer do not pay for themselves. People expect bank accounts with zero fees. This means that the payment infrastructure has to be cross subsidized from something unrelated to the payment infrastructure and that in turn means that the availability of the payment infrastructure is dependent on the actual cash cow of the bank.
Lending to borrowers and diverting interest means your payment infrastructure is now tied to the creditworthiness of debtors. Even worse, what if the margins are so thin the bank does investment banking instead? Now your payment infrastructure is tied to the erratic stock market!
The obvious solution is to stop the cross subsidy and start demanding that people pay for payment services separately. This doesn't guarantee proper and competent management. It merely makes it possible in the first place. Of course the problem is that various consumer protection agencies lobby for legislation that appears on its face to protect consumers but only by making the entire system less stable.
