I think this is more business point discussion for a platform (how do you motivate your users to create) than for a government how to enforce that creators are not being ripped off by users and platforms.

The case you described is already covered (at least in US) by the Fair Use doctrine [0] and works, well, works ok. I don't think the government should consider the use case of copyrighted work.
