Banks offer loans which help finance businesses. You have a pretty direct connection to people that actually work in the real economy. They are the ones that are paying the loans back after all. Nobody would be crazy enough to take a loan denominated in Bitcoin. The Bitcoin community is basically dedicated to making it impossible to repay debts. Just think about it, every HODLer that joins the community makes it harder to repay your debt because they will never spend their Bitcoin on things your company produces.

It's funny how low inflation or even deflation (if you consider 2% to be price stability) caused a rush of money into mortgage bonds and subsequently destabilized fiat currencies and cryptocurrencies try to beat fiat currencies on their way to becoming useless as a medium of exchange and subsequently make it useless for financing via debt.
