One question I like to propose to those who disagree with this sentiment is as follows:
Imagine you live in a hypothetical world where all things you consider moral, just and socially acceptable were legal and societally acceptable and where everything else was illegal and societally reprehensible. What role would privacy play in such a society? What benefits would it provide?
I have yet to get a good answer to that question; if peeing in public was ok with me, everyone else and perfectly legal, what reason would I have not to do it? (You can mention shaming and whatnot, but I posit that in this hypothetical world based on my morality, if I didn't shame people, no one else would either).
tl;dr: the problem isn't privacy, the problem is law and our inability to influence it, for which our best tool for the problems that arise from our lack of influence is privacy.
