You can use a banknote for an unlimited number of transactions, with no intermediary, and no tax per transaction. States and banks benefit by printing this tool for you, because in return they control the movement of money when it comes back to them, and its value. But with digital currency, they've hit the jackpot, realizing that they can have their cake and eat it too: they can control the movement of money, its value and even tax it on a per-transaction basis. And without any advantage other than saving space in your pocket.
