Banks can't work with bitcoin, search "fractional reserve". Banks may offer some Bitcoin services in future but it won't replace fiat services nor it will be possible to seamlessly juggle/ exchange between bitcoin and fiat.
Yes probably it has a point. I also believe that Bitcoin do not need banks in order to do transactions, it implies that bitcoin and bank cannot be a partner just like what fiat and bank has. The characteristics of bitcoin is the join force characteristics of bank and fiat. Bitcoin can work alone.
