If you're going to make these arguments about IP, you can also make them about property rights in general.
What is it about creative IP that makes it different to other kinds of family inheritance, or other kinds of rentier ownership?
Why does the argument that "Ownership rights should expire as soon as possible for the common good" not apply to huge land and property holdings, some of which have been passed down for centuries, with far more obvious economic and political effects than - say - Tolkien's descendants not needing a day job?
It is unfortunate and confusing that copyright and patents are described as intellectual "property" because intellectual property is fundamentally different than other property rights. Property laws as originally formulated applied to rivalrous goods where consumption by one consumer prevents consumption by others. Copyright and patents apply to non-rivalrous goods.
Rivalrous goods are relatively easier to protect and monetize without the assistance of the state. Non-rivalrous goods are pretty much impossible to protect/monetize without the assistance of a state.
A lot of physical "property rights" are equally dubious though and probably shouldn't have the reverence people have for them. The reason why land ownership reform (splitting up of big land holdings owned by the wealthy but farmed by the poor) was a big issue in 19th century Britain (and Ireland which was completely part of it then) and still is an issue in the developing world today, is ultimately it is arbitrary that somebody gets to "own" land just because they are descended from aristocrats who conquered it centuries ago.

No, physical property are both excludable and rivalrous goods [1], for them ownership is a natural right.
OTOH, IP are naturally non-rivalrous, and only semi-excludable through establishment of copyright law. IP ownership is just societal construct trying to fit market mechanisms to them.
>An anti-rival good is one where the more people share it, the more utility each person receives. It is the opposite of a rival good. Examples include software and other information goods created through the process of commons-based peer production. The term was coined by economist Steven Weber.

In general, property rights don't end when someone dies, they're just transferred to someone else. People can even take advantage of the fact that property rights endure by selling the right to take possession after their death.
