Frankly, people should be entitled to own their likenesses. I’m not a lawyer, but it seems like the examples they mention in the article; - parody, public figures, film rights, etc. - are already pretty well carved out in the courts.
I can’t just make a biopic about Michael Jackson… I would need rights to the footage and permission from his estate.
I can’t use a photo of Tom Hanks to promote a film he isn’t i, even if I took the photo (and therefore own it). If I don’t sign the release, they have to blur my face in a documentary.
Celebrities already have certain established rights to the use of their likeness, and in this day and age those rights should really extend to everyone.
