Sure, but then the logical step would be to charge producers and get them to charge viewers, either directly or via ads. But we all know that will result in the demise of the platform, so that's a no-no for both youtube and producers.

Your subscription money doesn't go to the producers anyway, or only little of it, so the $14/mo is for a large part Google's profit.

I'm not sure I would say your $14 doesn't go to the creators: they get paid per minute watched when the user has Premium. A while ago Lon Seidman published a video discussing his YouTube earnings, and he mentioned that Premium is actually much more remunerative for creators compared to traditional ads.
