Maybe I should clarify: Society, in general, supports the idea that writers, artists, film makers, coders, etc— everyone who creates IP- should have a place in the economy. Basically just that it should be possible to make a living and have a career at it. It can be spun different ways, and those differences are important, but this is the basic thing.
This doesn’t seem like a disputable statement to me. For anyone who thinks actors’ likenesses, authors’ words, all of it- that all and everything should be up for grabs once written or put anywhere in public, that is not a widely held opinion.
Once that’s established, it all comes down to implementation details.
It is strange that you think the law is settled when I don't think even this "societal desire" is completely settled just yet.
