Will Bitcoin replace banks just because it is more profitable than banks?

No offense, but if you think bitcoin will replace banks just because of that then you don't seem to understand the role and mission of banks in the world economy. Banks is not just an institution that deposits money and pays interest, or just a system that is used only to make payments. They are a very important financial institution because they provide most of the financial related services to help people, businesses and also help sustain our economy.

Can Bitcoin provide financial loans to businesses, provide insurance services, and more importantly, can it act on behalf of banks to regulate the economy through monetary policies?
