The main question is who will regulate decentralization at the world level: the system itself or the government?
Am I missing something? Why would decentralization need regulation? When you talk about regulation, it makes me thing of some governing body. Like there should be a government above decentralization. Wouldn't that be sort of an oxymoron? You said the Internet was initially decentralized. Do you think that's changed? I'm under the impression that the Internet is extremely decentralized. I've heard that it's near impossible to shut down the Internet because it is decentralized. To answer your question in short, decentralization shouldn't need regulation.
