Cannot, the bank is the official institution that full supported by the Government's, all done through the bank such as economic policy. bitcoin can't possibly eliminate and make the bank disappear even though used en masse.
That is the main reason why bitcoin can't make the banks disappear because banks are supported by the government and the government is one of the most powerful in the world who can manipulate and dictate something or someone else. Bitcoin can't make banks disappear but it can be an additional option for the banks in accepting payments like what some of the banks already did.
Well, at least we all know how powerful the government is, bitcoin is just a system and it will not be as powerful and popular like fiat.
Bank will only accept assets or fiat that is recognize by the government as legal, bitcoin is legal but it has different definition and it is just solely considered as a payment system. True that the demand will increase in the future due to the growing popularity but it cannot surpass fiat.
