For anyone hoping of using bitcoins for their everyday transactions, would that be any more anonymous than a credit card is today? Or even worse, it might give you the sense that you are anonymous when you are not.
If a payment technology can't be used to incentivize TOR nodes, it is not anonymous. Throwing around the word 'anonymity' when one means 'psuedonymity' does a disservice to everyone interested in actual anonymous systems.
