Why wouldn't the companies allow this if they own the IP? The cost/benefit calculus is just too good.
I can see them forbidding sexual stuff, but anything else would be clear. If they buy out actors' likenesses, and they will sell for the right price, especially if they get royalties. Imagine being an actor and getting paid to not actually act, just letting them sell your body/voice likeness to be used as a puppet for AI users.
I think that sets a dehumanizing precedent. One of the driving forces of humanity is innovation. We're legit probably going to see the end of innovation if everything is licensed out and behind a pay wall.
For instance, I'm a big fighting game fan... I bought street fight V 7 years ago or some shyt... IT WASN'T EVEN A fukkING COMPLETE GAME... I think I personally spent another $150 to get all of the features you would get from a completed game. Apply this logic to every other media platform... and then really apply it when there's ONLY 5 media companies right now, and someone like Warner/Discovery split recently so it's easier to sell off Warner Bros to an Amazon or an Apple.
It's the commodification of culture. Culture should never be commodified. It's why rap sucks right now. It's why every movie nowadays is some end of the world spectacle. Its a lack of innovative thought that only those with money will be able to access... which fine, that's one way to do it, but if wealth doesn't transfer amongst social classes, then the same people will own everything, and be able to effectively dictate culture in whatever manner that they want.
Again, Black Mirror shyt...
It sounds cool in theory, but I'm not really for it, because I know how corporatism pans out.
