So basically my idea of "(youtube) can't get the benefit of you using/watching something" is correct, but もらう can't be just attached to 利用 directly like いただく can? I always thought もらう and いただく were interchangeable in like all cases. Is there any special reason why 利用してもらえない wouldn't work like 利用いただけません from youtube's point of view (not taking politeness into account)? Or did I misunderstand something?
