This is definitely something interesting.... however, it is not important at all. Bitcoin doesn't need anonymity. Those who need it have things to hide...
I have seen this argument used over and over and it is annoying because people seem to not think it over when they say it. This is about our privacy and it is our right. Some people do not think like you, some of us actually want our privacy and our family's privacy protected. If you are going to say such things do not speak as if you are speaking for everyone.
I have nothing to hide, I have much to protect.
The "you have things to hide" argument is authoritarian pablum. It presumes that the law enforcement is ever present and entirely protective. It assumes that you can never protect yourself. Does the person who says this leave their valuable objects in clear view in their car overnight. Do they walk around naked?
Privacy is important for so many reasons, it is not about wrongdoing, it is about survival in a civil society.
