you can buy, for example used things, face to face, no one can track you in that way, or selling them , always face to face, to buy foods, foods is not trackable either
You can't track transaction (but still you you can track it), but as always it's easy when btc is transferred to fiat. or you buy thing (house, cars, etc). so anonymity is pretty far away.
Anonymity is just hype word all around the world because of NSA... Real value i believe is in quick transaction.
You should remember one year ago everybody was talking about how there is almost no fees (how banks earn on fees), funny thing if you calculate you pay more fees in crypto world than if you where using fiat in bank system. So that was debunked, now it's anonymity, than will be some other fancy fog word...
