I think they shouldn't be attached to that old business model in a world where self-publishing is possible.
I also think generous UBI should exist, but I guess that's another issue.
The key point is remembering that copyright isn't some divine right stemming from the muses blessing the author with their own exclusively-owned words; it's a right societies fabricate because we believe it will incentivize people to build new knowledge that eventually benefits everyone. It's that incentivization that's the goal.
I do think UBI should be a minimum, and people should still receive compensation for work they produce that people enjoy. Just not exclusive rights and perpetual royalties and all this nonsense.
