Couldn't have said it better myself! Privacy is first and foremost a discipline and a practice, just like security. It's a form of self-respect, in my eyes. Some would say it's even a natural human right.

Commoditizing it is a recipe for disaster.

Edit: Expansion of the self-respect tidbit. Lack of privacy enables others to have control over you. Feeling like you are not in control, or actually being controlled by someone (shame, blackmail, etc.) can be very damaging to your mental health. Respect yourself, strive for privacy. You deserve it as much as anyone else.
