I think everyone should use bitcoin, regardless of political boundaries. It's what ties everyone together, from me to some shithead scammer living in a dirt floor whorehouse in Africa. This is what I like. Governments should stay the fuck out.
Government should allow its citizens to own an use bitcoin. But government should also have a great role to play on the bitcoin transactions. Like fiat currency it should be regulated to foresee that it is not feeding illegal activities. There's no reason why we should be afraid of governtmeans having a say on bitcoins if we are not criminals or doing illegal activities then we are safe.
