I don't think you understand how copyrights work. If they are abolished, everybody is free to redistribute your creation without compensation or even acknowledgement. The moment you put it out there, it's instantly public domain.

That means we'd have no more professionally produced movies, series, books, songs, games, etc., but would be stuck with what's essentially fan art.

Sure, there are talented artists out there who produce music as a hobby, youtubers who make great videos and such, but it would be the end of commercial productions.
