A couple thoughts. Richard may be right that people value certain types of privacy very little, but I am not yet persuaded. To make his argument stronger, he should prove that people know the costs of disclosing their information. I am skeptical that people understand the costs of digitizing their information or using an EZPass. Perhaps they believe their information is safe and used only for very limited purposes.

On the broader topic, whether privacy will become less important, well, it matters what is being kept private. One's address can be found by almost anyone today and is probably all over the internet - perhaps this type of privacy is not valued much by the public. But what about the way you cast your vote, your sexual orientation, your religious beliefs? I think the premium for privacy in these areas is high. Concealment is important not because one wants to appear other than what they are, but rather, because they would prefer not to face discrimination from people (or governments) because of what they are.
