> Digital currencies allow for full tracking of every transaction
This is an implementation detail. Merely adding “digital currency” in the sense of “personal accounts at the treasury” isn’t proper cash replacement.
It is however possible to make a more anonymous kind of e-cash in which your transactions are not tracked. Chaum E-cash and similar ideas are useful cash-replacements. They aren’t without their on problems so e.g the Swedish central bank appears to be eyeing a double system where you have both types of system: a centralized/non-anonymous store and a token based type which provides anonymity. The latter could be used with a cap on transactions because if it’s properties wrt double spending.
