Discussions about Bitcoin replacing banks have been discussed even before Bitcoin was this big and you see the bigger Bitcoin is, the banks are still there and Bitcoin lovers still use banks to receive their Bitcoin sales to fiat.
People probably forgot that the main reason banks existed in the first place, was to have someone take care of your money, and to have someone loan you money to start a venture or to buy a house etc.
Bitcoin isn't going to take care of your money, you have to take care of your Bitcoin. And you won't be able to borrow a single cent from Bitcoin.
I think people really have to get things before claiming it, even if you love Bitcoin and never use a bank, Bitcoin didn't and never will replace the primary purposes of banks.
