Yup, like when the gov didn't like people using drugs and they started a war on drugs and now nobody can get or use drugs anymore.   

Guess what, they don't like people using bitcoin and encryption either. Do you think they will be any more successful at stopping it? 
They are perhaps just smart enough to know they shouldn't even try as it will just make people more aware of the gov's powerlessness
to control it. Any actions they take will be the desperate last swipes of the dying dragons tail...
