No i dont agree, it is like making bitcoin centralized, and that is all the opposite of what bitcoin was created for, so it is never going to happen unless that a cryptocurrency is created for that purpose (creating a bank) but i dont think that this is going to happen, and less in this times, that we are full of fuds between cryptocurrencies and banks.
So no, it wont happen soon
Some people here are so against centralization. If you are truly against centralization of bitcoin, then you should not use any trading site, any online wallet, or anything that makes a small centralization. Online wallets create centralization the same way a bitcoin bank creates it. A number of wallets falls under their hands. I think that the only difference with bitcoin banks (assuming that they are from the government) is that the common people will be a little relieved and so they will deposit their bitcoin in there. Some people are too afraid that their bitcoins will go to the hands of a hacker and so they cash out their bitcoins right away instead of holding it for a long time and earn huge profits.
I don't agree with the idea of bitcoin banks because it creates centralization but I can still bear the fact that there will always be centralization going on with bitcoin in some ways.
