How would you feel about someone taking pictures of you while you are using the restroom? clearly we should ban cameras from restrooms and remove all sorts of windows. In fact, we should demand all pictures taken with a camera to be submitted to a public archive, just to make sure no evil deeds are done.
... as people generally don't like pictures of them being taken of them while they are in the bathroom, we actually do have laws that state that it is illegal to do so; past that, your analogy doesn't hold: we don't require all software to be submitted to a central archive so as to enforce GPL.
