Property rights don't expire. Copyright does. These are very different systems based on fundamentally different principles. Reasoning about copyrights using analogies based on physical property such as houses is not particularly productive. If you want copyright to be something that can be inherited or otherwise gifted to someone else, a (short) fixed term like the original 28 year limit makes much more sense than anything based on the author's lifespan. There is no need to extent it "way past the original creator life". Most things that can potentially be inherited don't have longer lifetimes than their original owners. Even houses don't last forever. If they're still around they can be part of the estate; otherwise the heirs can inherit whatever is left of the invested earnings.
