The proper definition of a right also explains to what extent you have a right to privacy, which is to the extent that you have a right to property.  You have a right to property, which is to say a right to determine what you do with things over which you have control.  You can build a privacy fence around your house.  You do not have a right to control where other people turn their eyes.  Thus, if you stand outside your house, naked, without a privacy fence, you do not have a right to the privacy of your private parts in that context, because you would in that case be demanding not the freedom to act on your own behalf but that all passersby act according to your dictate (“Don’t look at me!  I have a right to privacy!”).

Indeed, we can better say that you have a right to property, and to the extent that you own property, you have the capability of privacy.
