I see. So if I build a house I can keep it as long as I live and leave it to my descendants in perpetuity; but if I write a novel then it belongs to the collective.
Not under current law no.
Imagine if a famous 16th century artist had modern day descendants, who felt that their paintings were now their inherited intellectual property, and forbid them from being printed in books.
Pictures and stories from the past are historic. They should belong to everybody.
Like all Intellectual property, if it is reproducible without loss of any original material, then it is distinguishable from things tangible like houses or gold bullion, and so should be treated differently in law, particularly with regard to when things age.
I think that people who want to make a living off the creative labors of previous generations, but offering nothing of their own merit, are a liability to the state.
