This argument would make sense if it was across the board, but it's impossible (and pretty ridiculous) to enforce in basically anything except very narrow types of media.
Let's say I come up with a groundbreaking workout routine. Some guy in the gym watches me for a while, adopts it, then goes on to become some sort of bodybuilding champion. I wouldn't be entitled to a portion of his winnings, that would be ridiculous.
Let's say I come up with a cool new fashion style. Someone sees my posts on insta and starts dressing similarly, then ends up with a massive following and starts making money in a modelling career. I wouldn't be entitled to a portion of their income, that would be ridiculous.
And yet, for some reason, media is special.
