"If you're not doing anything wrong, you have no reason to mind the constant surveillance." In some ways, it's a hard argument to counter -- I want to be free to break the law? But the intuitive response is the right one: it tends to put a damper on free discourse, to encourage self-censorship and a watch-your-ass mentality, which are thoroughly inimical to democracy. As Mrrzy's post suggests, it's not an all-or-nothing proposition: there's a world of difference in the privacy-vs.-public good tradeoff between recording the purchase of deadly weapons and tracking your every move and transaction. But maybe it'll be a shot in the arm for live, face-to-face, unrecorded events.
