It's a possibility. States do work to undermine things that threaten them. The Liberty Dollar project, for example, was recently shut down by the US government: http://en.wikipedia.org/wiki/Liberty_Dollar
Sure, and they shut it down openly using the hammer and anvil of the FBI and the judicial system. If and when the US Government decides to act against bitcoin, they'll do it loudly and openly... not by some complicated, difficult and illegal scheme that doesn't really achieve anything.
Currency issues fall into the jurisdiction of the US Secret Service, an agency not known for subtlety.
Yeah, if legal and open is more cost effective, they'll likely go that route. Otherwise, they may revert to skullduggery (as they have in the past: http://en.wikipedia.org/wiki/COINTELPRO).
COINTELPRO included "extralegal violence and assassination" according to Wikipedia. So it's weird to think that the authorities would rule out a bit of hacking to protect their interests.
