  Even when considering just ownership, there is debate amongst theorists as to how this should be analysed. Some see it as essentially a cluster of other property rights of particular content, such as those to possession, income, etc, whilst others see it as being basically a structural relation between rights, content being comparatively irrelevant. For example as being the person to whom possession or use, even though those may presently belong to others, would ultimately return if a certain series of contingent events were to occur.
