Privacy protects from abusive power, and privacy protects from irrational judgment: true but incomplete. Privacy allows us to tolerate these problems - rather than being forced to confront them. That may not be a good thing.
Society is full of things we compartmentalize, minimize and tolerate.
Mostly, because we don't know how to confront them. I certainly don't know how to patch human nature so that power doesn't corrupt. So, in the meantime, I'll take privacy, thanks.
