It depends on which kind of "works" we're talking about.
I seriously doubt that passionate authors would refrain themselves from writing because they've been denied a few extra bucks after their death. Many would probably be happier to know that their legacy goes on through the now possible derivative work.
Could such a restriction on copyright impact purely commercial works? I don't care. Work made just for profit has no soul anyway.
It's not after their death. This is the crazymaking part of the argument. The cash flows from art received after the death of the author is factored in to the compensation the artist obtains during their life. This is basic economics.
If you don't care about a work made for profit because it's soulless, then what grounds do you have to set terms for its release? It's work you by definition think is unimportant.
