Walker walks onto Proper's land and claims nobody can own land. This situation sees Proper's land put to a use he does not choose or want, and Walker contradicting himself by occupying the land and choosing how to dispose of wherever he stands - this situation is now a dispute between these two people.
Who is allowed to resolve the dispute and by which means?
a. Proper can act to get Walker off his land somehow.
b. Walker can act to get Proper off the land or restrain him so he can't not share it.
c. Neither can do anything and they just stare blankly at each other until they die of thirst
