But banks don't like this, if no one is borrowing from banks, how could they make a live? If there is no new money creation, the banks will die
If banks die the economy will die with them. Banking and finance is integral to free trade.
Banks works exactly like centralized bitcoin exchanges, they store customer money and play until they go broke, and ask for bailout by tax payer (unfortunately they can not claim to be hacked like a bitcoin exchange). Centralized bitcoin exchanges are not necessary, we have OTC market and localbitcoins, you can do person to person trade
In old time, a major reason that banks are needed is security, people need bank's vault to provide some protection for their saved money
