My biggest critique of copyright is that is unnecessarily collapses financial reward & creative control. It also pegs both as starting at creation - which is not a particularly meaningful point for either problem.

IMO I would rather a structure that:

- Guarantees creators (and their descendants) some number of years of financial benefit / veto (30 seems fine!) - i.e. pay me what I want or you can't use this creative work.

- Separately grant creators the ability to veto "official" projects that use their creative output in their lifetimes.

IMO, it seems like there's a productive "middle ground" between total control and anything goes. After the 30 year benefit expired, you couldn't sue for damages - just costs & to stop use.
