This is a great thread. You know, they have a great potential with that kind of anonymous payment system to centralize everything and keep it all under lock and key, so what's stopping them? I think that they have this in mind and are already slowly moving towards it (Sweden is something like 98% cashless now) just by getting people used to the fact that they don't need physical currency anymore. Then what? Slip them across from the Swedish Krona to the e-Krona, and just change the terms slightly. Many more countries will begin to follow suit. And I don't think it will necessarily be fully anonymous, in fact, they might even sell the information to the highest bidding market research firm.
