IP is a granted permissions by the state. It can not be owned by the individual.
The same goes for any other form of permissions. If I get a government permission to sell drugs or produce weapons, I would not call that a property right, comparable to the car I own. The permission to enter a house is not comparable to the property right of the person who owns the house.
If we look at copyright specific, it is an intrusion into the property right of others. Its not just a permissions, but also a restrictions of the actually property owners rights. By calling copyright a property equal to physical objects, we are making the term property meaningless to the point of contradiction.
All "property rights" are sets of permissions granted by the state to an individual (or legal entity) to certain exclusive privileges with regard to whatever it is the "property right" relates to. This is just as true of rights to tangible personal property (like an iPhone) or real property (like a house) as it is to intellectual property (like a copyright), or intangible personal property that is not intellectual property (like a stock).
