For not to lose their power on their economy, governors would not accept any external power. Decentralization means millions of investors and users who are not under control. I am agree with governors' thought at some scale. But it changes when I look to how governors use their power on their economy. They prefer to use this power on their behalf, not behalf of all citiziens. They make rich more rich and poor more poor. There is still a cast system in every country. By using traditional tools, it is nearly impossible to overcome this cast system. Bitcoin may not be the tool for it. I don't know exactly. All I know is it might be initiator for people to search for way out.
Tracking people is something that the government wants, and through the all the cryptocurrencies it is not 100% possible but at least they can.
They set laws for crypto people that should pass KYC if they want to convert the crypto into fiat and vise versa.
