Why privacy matters even if you have nothing to hide (central ideas)

well you actually do have things to hide

Explanation:

The "if you have nothing to hide ... " line is predicated on the viewer having final say about whether something is right/wrong, thus subordinating the subject to the viewer. This is repulsive to the notion of liberty as protected by the American "4th Amendment" right of freedom from governmental inspection without an adjudicated warrant. To wit: it's not that I have something to hide, it's that someone else is going to be obnoxious if they see it.
