I think people should never underestimate the power of governments and why Fiat currencies are so important to them. Satoshi Nakamoto (Bitcoin) only succeeded with the Denationalization of Money, because Satoshi Nakamoto stayed anonymous and the technology was decentralized.
If the government knew who Satoshi Nakamoto was... they would have prosecuted Satoshi with the full force of the law and they would have had some way to make an example of people that wants to create their own "Private" currencies. ( Example : Bernard von NotHaus and the

https://en.wikipedia.org/wiki/Liberty_dollar_(private_currency) - They (government) labelled Bernard von NotHaus as a Economic Terrorist and the Justice Department press release was quoted as saying: "While these forms of anti-government activities do not involve violence, they are every bit as insidious and represent a clear and present danger to the economic stability of this country."
That is literally the only reason why he is not coming out as well, or maybe he can't anymore because he might be dead but that's not the point. Dude knew that if he came out then there would be a huge problem, wherever he is from, wherever he is living, wherever he wants to go to all of that would be in search for him and putting him in jail and trying to make a point with it as well, they would throw the whole book at him just to make a statement.
In short, if we are talking about something that is giving people freedom over their governments, even if it is not illegal then governments will try to do their best to stop it and move with their own path, anything that changes the path of the government will be seen as bad. Look at what's going on all around the world, when people start to give power and money to whole groups to give them more freedom, those creators will always be seen as bad by many people.
