I don't think it should be taken as obvious that authors profiting off old works is a deserved right or positive.

Game of Thrones was originally published in 1996, but the more recent books are more recent. I think that GRR Martin's books would be giving him sizeable profit, even if someone else were able to make GoT fanfiction in the same universe, and the GoT TV Series would still have to pay him to use the more recent copyrighted books, not just the settings and characters from the original.

There is already intrinsic value in having written the original work, and that intrinsic value will make you the best person to consult on a TV adaption or make sequels, even if the original work is public domain and in theory anyone could adapt it.

If an author makes something 20 years ago, doesn't build on the universe any more beyond that, and is unable to compete in their own universe they built against other authors once it goes public domain and becomes popular, well, then tough luck for the author.

Let's look at how this works for software: every piece of open-source software out there is something that in theory another company could take and sell as their own. Red Hat Linux is Open Source, so sure anyone can make their own... and yet Red Hat can sell consulting services and new versions of it because they're the only group with proper expertise there.

> limit the number of copyrights held by a particular entity

Entities are unfortunately quite easy to fake and difficult to define in a fool-proof way.

If you can still license copyrights, then holding companies would become the norm. Like, right now LucasArts owns StarWars, and LucasArts is a wholly-owned subsidiary of Disney, but if we had a limit on how many copyrights an entity can hold, Disney wouldn't acquire LucasArts, and would instead pay for an exclusive copyright license.
