> Speed cameras are different.

So basically your entire argument revolves around the government pinky-promising that it won't use the data from speed cameras to track innocent citizens. Because when the network is dense enough, you can tell who went exactly when and where. This isn't any different from Amazon pinky-promising that it will only use data to improve customer experience.

The bigger point I'm making is that mass-surveilance technology does have benefits to the society, and any absolutist "but but but my privacy" who fails to acknowledge them is doomed to lose the debate.
