People are acting like a "deepfake of a person" is something different than a drawing, painting, song, poem or any other artistic creation inspired by, based on, or with elements drawn from a real person.
"If someone is deepfaking you" is such a weird imaginary problem. Someone might be imagining you. Someone might see you in a coffee shop while writing a screenplay and use the outfit you're wearing to describe a character in their story. Who cares?
If someone is committing fraud by trying to pass off a deepfake as a real photo, then we already have laws around fraud, defamation, harassment to cover that. If someone makes a deepfake that looks similar to a real person for their own amusement, that's no different than writing fan-fiction or sketching in a notebook.
