>For copyright owned by individuals, why should a creator's children and grandchildren (and great-grandchildren?) be allowed to continue to profit off their ancestor's work, depriving the commons of history and culture? If the copyrighted works were still relevant enough to the culture that the creator's descendants are still profiting off of the work, I don't see how it could be lost to the commons. If the commons and culture no longer care enough about the work to offer any money for it, I don't see how the descendants could still be profiting from the work. I don't have a dog in this fight (outside of me bristling at people acting entitled to disregard terms of GPL copylefts), I just what whatever system will optimize the quantity+quality of creative works, and I want creators to get paid adequate value for their work, even if that means they can sell the rights to their work to another entity.
