It's not a human construct. If you have ever spent time around a cat, you can understand ownership completely without any legal constructs. What we as humans are somewhat proud of, or the definition of civilization, is that we spend most of our time trying to create systems to define boundaries and property rights without resorting to violence. Those systems can be fair and well-distributed or unfair and hereditary, or somewhere in-between; they inevitably hand over the violence to some arbiter or government (whether market-driven or communist dictatorship, it's the same in terms of a structure enforcing who gets what, even if the incentives and dynamics are skewed); but the point is that we code them into law so that any arbitrary cat can't just post up inside another cat's borders and terrorize the house. The point of PROPERTY writ large isn't the piracy or acts of violence that people here make it out to be. Property doesn't arise from the law. Legal frameworks arise from the existence of property. And legal frameworks are an unadorned good in a world without them, because normal, domestic, and peaceful life does not exist where laws don't exist.
