I just disagree with your opinion of the ability of the US government to shut down things like this. In my opinion all the governments in the world, working together cooperatively (which can never happen) could not shut down internet hacking groups.
The US government hasn't shut down Anonymous. They haven't shut down Wikileaks despite their pressure on the governments of 3 countries whose governments play a part in delivering Assange to the US, and despite their suspected involvement in setting up the alternative leak site OpenLeaks which was talked about here but still has not gotten off the ground and has become a joke. The US government took a lot of years to kill Osama bin Laden. The US government to the best of my knowledge hasn't gotten one conviction upheld of any Guantanemo detainee (except for a handful that plea bargained). Those are a few recent examples on which I base my opinion.
The government has less power than you think, in my opinion. They have a lot of time, a lot of resources, a national security budget the public never gets to see, but they are often big and stumbling and are certainly not all powerful.
If every member of Anonymous was killed today there would be another equally skilled group doing the same thing inside a year.--
