Maybe the money printed by the central banks is not needed

Money is the medium of exchange, this is the concept of money. Moreover, money itself can circulate in the society independently. The main character money should have is everyone agrees on the value of money. Therefore, if we can have one thing that has these three characters, it can be used as money, even if it is not produced by the government. We can find this type of things: for example, gift cards. Gift cards are not made by any government institutions or banks, they are made by companies and have all these three characters. If one day all companies have their gift cards and different companies’ gift cards are exchanged without any limited, then why do we need the money printed by the central bank? When such exchange happens more frequently, the society itself will start to allow the companies to issue money in terms of the values of their production. The only role of the government in the field of monetary would be the watchdog of the markets.
