True, but at least Taler allows for the consumer to chose merchants who specify they don't sell data. Right now I can't buy anything online and not be tracked by the payment provider unless I use bitcoin. The prepaid credit cards here all require online registration and in store identification, Visa/Mc/Amex then track my purchases. If I show ID to buy $200 worth of Taler in a 7-11, there's no way for my Taler provider to see what I used it for.
