Privacy absolutely should be a human right. But currently it isn't, and part of why is there is lots of money to be made with surveillance on ordinary people. And things will not change unless the people who exploit the privacy of other for monetary gain feel the effects of their privacy being violated.
Human rights are routinely revoked from those that impede on the rights of others. This is the premise that underpins prisons.
Privacy being a human right still holds true.
