? You're confusing security with anonymity. The bitcoin mining strategy ensures that transactions are secure, untampered (ID theft? counterfeit bills? credit hijacking?), thus securing anonymity if it is developed (throw away accounts, as said above) when and where needed.

The problem with classical currency is that anyone can spoof anyone else and the system inherently cannot prevent this. Fraud correction is a painstaking manual/organic process involving customer service, account IDs, and headache.
