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.
They are idealizing a pay-the-creator system. They are arguing for a system that is kinda coming together with patreon-like stuff.
You seem to be arguing that people will just buy the cheapest identical copy. Which is hard to argue against, but there are people out there that pay creators that give their work for free. Copyright law certainly protects creators. But it’s cool to see some creators monetizing on open-licensed work.
