Not being aggressed upon is a right. A certain amount of privacy is written into the fabric of the universe and is impossible to take away, thankfully, because privacy is requisite to avoid being aggressed upon. The hiding of information is fundamental to the very possibility of property, and to the nature of reality as not being under the fiat thumb of any human or "collective" consciousness. Privacy is written into the rules that govern physics itself. It is not the fundamental of natural law, however. Nonaggression is.
