So Doc , basically what you are advocating is a cashless society where all transactions are made with some sort of electrical device where all your money is locked into some financial institution . A couple of upsides for the banks and governments , lots of downside for the consumer . The general public go absolutely berserk when their facebook or twitter goes down , could you imagine if they could not make a transaction , there goes your utopian future . A jar of lovely homemade sweet mustard pickles for half a dozen eggs , just simplistic .
