I think the fundamental question is: Without the government people, who will protect us from the other people, just like them, who will tax, confiscate and kill us?
Yes, we also need them to confuse us about the purpose of government, and to tell us that the alternative government people out there (IS, Russia) are worse.
The governments of all countries are not same and when we talk or think about the government the first thing comes to our mind is the corruption. Most of the government employees are involved in scams or corrupted activities so it becomes difficult for a ordinary person to trust them and when it comes to bitcoin I don't think that corrupted government will come in support of bitcoin.
The Government in my country will never accept it as a national currency as the Government themselves are involved in corruption so why they would support such thing which would be full stop to their corrupted activities?? The only thing we need is the adoption from the people and for that Government has no control.
