The world should not be a place without law. Even we can disagree with a lot of things launched by governments and central banks, we must recognize that they somewhat govern societies and keep things on the right track.
Without laws, without regulations, without governments, the world would be a very chaotic place that is not what I want to live in. I guess most of us don't want to live in a society without law and regulations too.
In my opinion, I agree that "Regulation is a good thing".
Government regulation can look at this issue from different roles. As a government, they hope that the economy will be in order, and they will think that the huge volatility of Bitcoin price is difficult to be used as an asset store, and it is difficult to enter the currency payment channel. But as investors, the volatility of Bitcoin is a tool and channel for them to make money, and they can do some things that they don't want others to know. In the long run, I am not in favor of regulation, because all I want is more freedom, a few decades of life, and I want to be in charge of myself.
