Here's a proposition: currently on RP sites, almost everybody uses AI to generate an avatar or portrait, rather than commissioning an artist or drawing it themselves; it's extremely easy to get detailed semirealistic art which sort of resembles your original character. And what I imagine will eventually happen is that an AI avatar will be considered low-status compared to art which is evidently drawn by a human. Because a thing that anyone can instantly get for free isn't exclusive enough to stay valuable for long.
That's assuming every LLM art compiler doesn't go bankrupt and the images they generated don't become "collectibles" as a result.
