Wow, just think about it how much money will go to Obama... Now IRS may have the best interest to keep Sotoshi safe, whoever he/she is. 
How it has not been converted to FIAT so they have no way to get him for taxes.
This as we can all verify that the Bitcoins have not moved no fiat gain means no taxes
EDIT: Sure they can go after Sotoshi no one knows who he is
