No. I'm of the opinion that banks still play an integrate part in the financial system of every economy. Without banks, the economy can't normally operate. The function of crypto isn't the same as that of banks. Banks make capital move from surplus to deficit, cryptos can't do that.
Siding your point, banks do play a vital and financial role in the system of economy.
Though evidently true that bitcoin can operate without a bank in between, banks will be around until unless governments decides to accept bitcoin as a legal tender with full backing of the governing authorities.
Additionaly, as long as the government is happy with the centralized power banks gave them, i think banks are here to stay. And we too can expect that a year from now, we will start seeing banks embrace cryptocurrency too.
