The same goes for actors and their likenesses ... just stop protecting ultra wealthy celebrities. They'll be a bit poorer, but they're going to be okay. You're just holding back progress
I can imagine in a decade some place like China which doesn't care about protecting celebrities will have movies with dozens of Tom Cruises Arnolds and Johansson's and will just be pumping out better quality content at affordable budgets. Young talented directors won't be hamstrung by these legal roadblocks
You're basically suggesting that it's okay to copy anyone's voice and appearance without ever giving them compensation and without regard to personality rights. That's insane. Even for someone who thinks this should be allowed in principle (I certainly don't think so), there would need to be strict safeguards. Or, do you want your person and voice to appear in a commercial for <insert organization, product, or cause you don't support at all and despise>?
Or do you suggest to have different laws for celebrities and poor actors?
