You're free to give away your work. Stop telling others what to do with their work and that you want to take it because they died.
And an appeal to putting all your eggs in one basket and then demanding that eggs remain valuable long after you're dead and replicators are invented.
Also, why does your family get to shirk their obligation to contribute to society?
> Stop telling others what to do with their work
We are not telling them what to do we are saying authors shouldn't have the right to restrict what we can do, or to be more precise, say - because that's what copyright is in the end, a limitation on free speech.
What about the families of people who toil over creative work and don't hit the jackpot? There are many fine writers/artists who never gain more than a niche audience while garbage sells big. Go to a bookstore and look at the history section, pseudo-historians like Bill O'Reilly are given more shelf space than serious historians. To be frank I almost exclusively buy from used book stores for the last decade because nonfiction offerings in chain/non-specialist bookstores are so bad. Vendors of used books tend to select for quality rather than popularity.
