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.
