I don't see what so huge here! Governments can pretty much seize anything and everything off of you if the want to and if they have a valid reason according to them.
Agreed. What's the big deal? This is the nature of the world we live in and coins will not be exempt any more than someone's collection of Orca penises. It sucks the big one but getting riled about it is about as comical as people on here deciding they shouldn't pay tax on them because it's, like, on the internet.
Wake me up when they find a way to intercept transactions on the blockchain itself.
