This will annoy the libertarian crowd, but a truly anonymous and untraceable medium of exchange is not only most likely impossible, but also undesirable. The failed war on drugs aside, a lot of the things people want to do completely anonymously are illegal for good reasons (CP, human trafficking, etc).
Does child pornography make cameras "undesirable"? How about USB external hard drives? Or the Internet?
Does human trafficking make chains and locks "undesirable"? White cargo vans with blacked-out windows? Freeways?
Seriously, let's focus on attacking the unjust behavior itself, not blaming tools and implements that have no inherent intent or character, for good or for evil.
Cameras, USB HDDs and the internet -- the non undesirable uses far outweigh the criminal ones. I'm not an ideologue, I'm a pragmatist.
Freeways is an interesting one, most places license people to drive, for very good reasons (just one of them being a help to law enforcement).
It seems like a bit of silly argument considering I don't believe a truly anonymous untraceable currency is possible but let's suppose it is. My pessimistic nature makes me think that the top 3 things it would be used for would be tax evasion, bribery and extortion.
