Non-cash money is certainly a step forward, but when the state will go completely cashless in addition to the convenience it will bring the risk of falling under total control of the government. We may further lose the freedom of our costs.
That's about the most beautiful part of all of this! It can only be "controlled" by the government in accordance with how capable they are to actually enforce an arbitrary, not necessarily fair set of rules. One where they skim money off the top at every level of movement...
But once your "money" is in the digital realm, they've got no control over what happens to it. It can move ALL AROUND the entire digital world and they can't touch it, try to tax it, try to steal it from you, etc.
Put differently, governments can control what happens within their borders - at least to the extent that they're actually able to govern, regulate, and capitalize on what happens within their borders. Exchanges that deal in fiat money are the perfect example. They can charge fees to convert to and from fiat dollars. But they can't control what you do with those currencies of value in the digital realm.
Any price controls that they attempt to impose can be superseded directly by the people in any given market/community/economy.
