Does any nation have a constitutional clause guaranteeing a right to anonymity? If not, then why is it more important than privacy?
Some mention a need for anonymity (not just privacy) with certain operations such as voting. I don't think many talk much about anonymity, but then many such documents were written long before the surveillance apparatus we have today was established.
Part of the reason real anonymity is important is that these days, privacy is often breached when it should not be. I believe that as we head further into the digital age, the distinction between "anonymous" and "private" will continue to grow, and the distinction between "private" and "public" will continue to shrink.
