I don't know, but I wonder if your parent commenter is making a philosophical point about the potentially illusory nature of owning a group of semi-wild animals. Like, if the only way you have of asserting your ownership is to use them as a food source, then do you really "own" them? Or do they exist outside and apart from human ideas of property?
Or like owning a mountain or a centuries-old tree. Does that even mean anything?
