In every scenario you come up with, you have it backward. The reality is that we currently have well argued law addressing all of these sick, twisted, and bad behavior scenarios you've drawn, without relying on arguments of rights to privacy. Through the ages the term "privacy" has been insurmountably ambiguous and hence legally undefinable for all practical purposes. The further reality is that should we succeed at making right to privacy a legal construct, the only impact it would have would be to open up a vast new avenue for people who engage in bad behavior to argue in defense of their bad behavior. So I find it ironic that you disagree with Professor Blockhead on this particular issue of [imaginary] rights.
