The universe in which we live is real, purely physical, comprised of matter (arrangements of information) and information (arrangements of matter) in space. We produce physical works, comprising both matter and information, a material and intellectual component. We can put these works into physical boxes and physically exclude others from them. We can call those works property, because they are alienable and we naturally have the power to exclude others from them.

Being intelligent, we can think/imagine in terms of abstractions, and can conceive of a non-existent/abstract plane in which abstract ideas permeate. One might term this an ‘intellectual space’. However, if we start confusing the abstract with the real, and start believing that, despite a lack of physical power within the abstract plane, people have some kind of divine right to exclude others from the abstractions they ‘homestead’ within that abstract plane (or ‘intellectual space’) then we join the ranks of what can be termed ‘religious nutters’.
