yes,bitcoin works like the bank and ATM.if want make transactions we no need depend on the banks,we can make direct transactions through the bitcoin address.the people who face problems with banks can happily change to bitcoin.banks transaction charges is very high,so bitcoin is best options to transfer and receive online payments.
Bitcoin has high fees too specially if you would transfer a small amount. I think there is almost no difference when it comes to fees now.
No matter how we wish that banks would disappear, I think they will always be there. It is not just the money that is in the bank, the people that are operating it are not just ordinary businessman, they are knowledgeable on what they are doing,so I think they can cope up in the future.
