I'm saying that
even abolishing copyright law might be an improvement. I didn't imply that that was the best idea (definitely not). Preferably copyright should be replaced by something that better promotes the arts and sciences.

Even so: to respond to who would create even if copyright law would be abolished:
A lot of people create with the intent of letting everyone instantly get to use their hard work. This is actually rather common. Huge amounts of fan-art, original art, original fiction and original fiction get created every day. Scientific articles get written every day. Wikipedia gets written every day. Open source software gets written every day. And let's not start about AI art and AI text (which currently is all PD) . 90% of this all might be crap, but then 90% of everything is crap. There are definitely gems among the 10%, just like everywhere else. And due to the sheer volume: there are a lot of gems.
Much of this activity would still happen without copyright law. There is clearly sufficient incentive at least. Fun is a common incentive. Sharing back is a common incentive too. Advancing the course of science. Earning fame.
Or you can just earn money. People earn money this way. I earn money this way. In this kind of situation, you pay the bills by "making things that don't exist yet".
Current copyright law has actually often gotten in the way more than that it has helped, I feel. I can tell you stories if you like! This does differ a bit per field and profession, of course.

But really copyright law should be replaced:
If you actually want to earn money by depending on copyright law, I feel you're getting short-changed at the moment. AI will "steal" your style; youtube, spotify and amazon will pay you mere pennies, of which apple might will pinch a percentage, your publisher will pinch a percentage, and you get left with ... very little.
Copyright frankly isn't helping many people right now. I don't think anyone is happy. Unless you know a bevy of small creators now living in mansions in Beverly Hills? I'd love to hear of it!
