The only way you can stop the government from having this power, is to hide the mining pools so the government can't find them (the servers).
Not only is this very possible, it is our civic duty to do so. Government employees must be shown their limitations to power that are already clearly laid out in the US Constitution.
How is it possible now? I am guessing you don't have a technological noodle to contemplate what you are saying.
I was confused by your statement regarding the blocking of private keys. It is very strange that you think government can have any control over Bitcoin at all. You seem to think you speak for most people. I disagree.
Huh? Where is your rebuttal to the fact that the government can regulate the mining pools?
Since all we're doing here is engaging in hypotheticals, I'll take a shot. TOR can obfuscate enough to make whackamole very time consuming. There is a plethora of black markets already using the technology as well as legitimate businesses that prefer privacy. It would be good for Bitcoin to minimize pool mining anyway. It's not risk of government censure that I see to threaten pools, but extreme corporate espionage. When Bitcoin gets to a certain level, miners will need to secure their facilities and pools even more so. At some point mining pools will develop their own proprietary obfuscation networks. It's not so much about hiding money, but more about privacy and security.
