I don't understand the anonymity argument. Cash is already anonymous - the act of transferring cash from one person to the other is anonymous. While bills have serial numbers, it is impossible to see who owns all the bills at any moment in time. One can only trace specific bills if they've been marked and then found. Bitcoin transactions are not only recorded, but linked to each other uniquely. It's a government's dream to be able to track all your payments everywhere. It's the opposite of anonymity. Even if you manage to buy bitcoins from someone anonymously, if you _ever_ make a transaction that identifies you (such as paying with Bitcoin at Starbucks where a security camera can run facial recognition) they can trace where your bitcoins came from and then look at all other transactions you've ever made. That situation is not better than fiat. It's an objectively worse situation for preserving your anonymity.
