That's one way of looking at it. I think there is a place for both - the banking system and bitcoin. bitcoin is a very interesting financial instrument that allows trustless transfers of money, while the banking system allows credit as an instrument to do things like finance homes, cars, etc. Credit is a really tough problem for bitcoin to solve, since banks can create currency.
