Your misunderstanding of "private data". This is not lawyered words.
> Saying that the provenance of a naked image of myself
It is not a naked image of yourself.
An image of someone else's naked body does not become a reflection of an image of you just because your face is pasted on it. Object if you wish, but when it comes to privacy, the only possible breach is of the privacy of the body, not the face.
> is relevant to the fact that it's a naked image of _me_ and I don't have ownership over my own image
