Yeah, that's good stuff! This part jumped out at me. In response to the claim that Bitcoin is "unregulated":
Virtual currencies are tightly regulated, by the market, and the software that orders those markets. This is the only regulation that matters. A more accurate description would be extralegal, since there is no law governing Bitcoin or systems like it. Bitcoin is usable not by a ‘specific virtual community’ but by everyone everywhere.
That's a great point. Bitcoin IS regulated. It's just that Bitcoin's regulation is accomplished by open-source code and the consensus of those who use it. In contrast, fiat regulation is accomplished by men with guns and the private machinations of a financial elite. Consensus and transparency versus violence and secrecy. Seems like a pretty clear choice, no?
