I think corporate ownership of copyrights is where things get complicated. The corporation is immortal, but not allowing corporations to hold copyright is probably too restrictive.
There is also a case to be made for life of the creator + X years (where X is reasonable) copyright term, in order to avoid systematically reducing the value of work by older creators.
I’m just happy that nobody could be arsed renewing most of the magazine science fiction from the pre-1963 era. Project Gutenberg has quite an assortment.
