This is a bit weird since normally copyright applies to works that someone has created. Typically they also have to involve creativity. For example, you can't protect a database with copyright, nor can you protect the rules of a game. But, you can protect the text used to explain the rules since that is something creative.

Your voice and body aren't typically seen as creative works. They're just the result of a genetic lottery played by your parents. But, I can vaguely see how you might be able to twist the typical rules to make it count. For example, people decide on hair styles and grooming. They choose their clothing and sometimes make-up. There is a creative process there and their body is the canvas. With that kind of concept of a body being a "creative work", any photograph of that body becomes a derivative work, as would any AI version of that person.

But, this seems like the wrong approach to me. If someone has a copyright on their body, then under typical copyright rules, they can assign their copyright to someone else. Most likely, a model would have to assign the right to her body's copyright to a modelling agency. After she did that, she couldn't even take a selfie because she'd be infringing on the modelling agency's copyright.

Privacy rules make more sense, look at Germany's photographic privacy laws for example.

If the focus is on copyright, then if someone sneaks a camera into a changing room, they can only be charged with copyright violations. If they give the photos away for free, then in many cases the punishment for copyright infringement is minimal. But, if the laws are about protecting privacy, then it doesn't matter if it was a commercial copyright infringement or if it was simply collecting someone's nude photo for personal use. The issue isn't the copyright infringement, it's the privacy violation.
