Exactly, I completely agree with you. This is what baffled me about the parent comment: "Unlike other human rights, the right to privacy has always been a bit fuzzy with a ton of exceptions and caveats".

Compare the right to privacy with other human rights, and I find it as clear and succinct as its counterparts (if not clearer and more succinct in some cases).

At the same time, given the international nature of these laws, I disagree with you on their problematic nature. They are (in my view) meant as a basis of diplomatic debate and not enforcement (which would be impracticable). They are to be complemented by organic law, because on their own they are unenforceable.
