Perhaps your belief and information is incorrect?
If you are aware of world events such as in Syria, you may be able to access anonymous/encrypted data figures from their country(for ex. Syrian public/people/ citizens... usage of "hidemyass type" software to get videos, info, etc. out of Syria) that data will indicate clearly 3 things....
1.) Syrians are using "hidemyass" type of web/software, which incidentally, was initially developed by the US Navy for sigops for anonymous and secure coms.
2) The Assad Regime is of course aware, has installed counter measures, and is likely capturing and torturing those involved in order to deter info from leaving Syria.
3) As the Assad regime figured out the "whistleblowers" captured and tortured them, all of a sudden, the usage of the "anonymous" software and web access dropped dramatically.
So if a third world, backwards regime can track anonymous users, wouldn't it be logical and probable that other countries and their National Security and LE agencies could too.
Finally IIRC the biggest? hoster of child *advertiser censored* was busted this month by the FBI, and that web and website and the software to access it is anonymous, encrypted, hidden, spread among numerous nodes, computers etc, etc.

So no. One is, as I said in a previous post, "anonymous" in laymen's terms but not necessarily in the " absolute" in computer science/technical/real world terms.
I will try and find the supporting data mentioned in this post, give me a minute
ETA.....here is the chart of Daily Direct Access Users in Syria up to June 2013. You will notice the severe drop in the Syrian public's use of "hidemyass type" also known as "anonymous" software due to detection by Syrian Authorities/Government of Damascus.
