You have the draw the line somewhere and using physical boundaries is quite useful. It create a natural distinction.<p>The problem with IP is that there isn&#x27;t any limit to it. A driver license is not more or less a property than a patent, but it acts wastingly different. Can I sell a driver license? can I rent it? Can I cut it into two different part and give a friend half of it? What makes the exclusivity of state granted driver license a non-property, in contrast to the state granted exclusivity of an patent?
