Being labeled Satoshi regardless of truth is pretty much going to get you robbed, kidnapped or killed. This dude lives in this town and has $400M of untraceable currency? The article gives his name, face, address and relatives. You can be sure as hell that somebody will do something stupid to try and get to it. I wouldn't wish this label upon anybody, it's exactly why the community tries to avoid speculating about it…
It is hardly untraceable. I hear Bitcoin advocates frequently claim that government has an interest in "shutting down Bitcoin", but compared to the all-cash industry of most organized crime, Bitcoin's pseudonymity is law enforcement's dream come true. A state actor would merely have to obtain the identity of one key in a series of transactions on the blockchain, and would gain far more information than any informant…
With bitcoin, sure you can trace coins, but laundering services (namely things like exchanges) can make you disappear a bit quicker.
Overall, though, bitcoin is the IRS' dream.
