That's the point. You don't need for people not to be able to see to feel private.
Feeling private does not mean having privacy.
You absolutely do need for people not to see in order to have privacy. That reality-TV celebrity and that Asian family do not have privacy, only the illusion thereof. That illusion has some psychological value, but not nearly as much as the real thing. As for the guy in the bathroom and the couple in the room with the tie on the door, you don't know what they're actually doing at all, and it is for that reason that they have privacy.
People will always have secrets, they will always find ways to keep them, and they will always have perfectly legitimate reasons for doing so. Your own use of a pseudonym is implicit but irrevocable agreement with that latter fact.
That illusion is what you have now, and have had for a very long time. Try to understand that. You don't have secrets. You really don't. Your secrets are known by a select group of people that you don't know, and they are for sale. That is the status quo you are defending. That is the status quo I am opposed to. I am not speaking in favour of putting cameras in your bedroom. I am speaking in favour of expanding the "select group that is in the know" to include you.
