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.
That's the same thing.
No one can use my stuff..........(unless you pay me royalties).
You can certainly pay the rights holder to use their property! Still! You could do it even without copyright I suppose. However, I think a space where it costs time and money for the rights holder to try to stop use and they won't get paid for it is super useful.
Consider this in the case of software as well - you get ~30 years of benefit from your work, but you can refuse to allow companies to incorporate it into their products as long as you live. Whichever companies you want! You can also not do that.
