The right to privacy has too often been a sheepskin to disguise wolves. The left has a policy they wish to enact and can not get it done legislatively. They then redress their policy preference in the sheepskin of "right to privacy" and then they get the judiciary to rule in favor of that policy.
Obviously the right to privacy can lead to patently absurd outcomes, and these outcomes are getting closer to reality.
Privacy in and of itself is not a right.
