People disagree about the reality of global warming. Does that mean we throw out the entire system of laws of the United States and other world powers because it hasn't yet addressed this problem?
This is exactly why I never bought the concept of BitCoin as a 'libertarian' currency. There's always politics, there's always governance. It becomes political as soon as more than one person is involved. And as soon as it's political, institutions, processes, procedures, and laws become necessary - also known as "government."
I still believe in BitCoin, however. Ultimately, there's a way out of this tangle, and like with most political problems, it's a political solution. BitCoin will either adapt and scale up or stay the same and scale (way) down.
