If everyone starts using electronic money, infrastructure will also need to be developed proportionately. It will not take too much time for paper money to disappear from the market. At the present time, it is not yet clear whether financial institutions can adapt to that change in a timely manner.
"It will not take much time for paper money to disappear from the market...", this statement is quite presumptuous. We need to understand that it is very difficult to change a system that has been around for a long period of time and has been accepted by the majority. I'm not saying it's impossible to do such a thing, but i can only see such a thing to happen in the far future.
