You can say 'rivalrous' as many times as you want, but none of this explains why an IP asset should suddenly be public domain when someone dies. You didn't answer any of the questions about various scenarios like company ownership or lots of people being involved in something's creation. Also there are already time limits for things to be in the public domain and medicine patents expire and become public domain, so I'm not sure what your point is.
