> We also can't ask the corrupt official whether he wants his communication to be traceable and seizable, yet cryptography enables him. I take the point, but communications privacy is much more of a cultural norm than an individual choosing whether or not to pay tax. We could live in a world of communications privacy far more easily than a world without government. Also, from a technical point of view, communications are pure data (with an origin and a destination), a currency is much, much more. The ability to hide data is not enough to make a currency functional.
