I think this is simply an extension of the fact that its really no longer possible to live an anonymous life in the USA. The government makes the case that they need to know who and where everyone is so that they can figure out who is "dangerous". This seems perfectly reasonable to an awful lot of people. The problem is that the people's idea of what "dangerous" means is wildly divergent from the government's.
