There is no scarcity of resources for the bears because here bears use a form of violent authoritarianism to ensure resource (salmon in your example) availability for themselves. A dominate bear will kill weaker bears to ensure food, mates, and territory are established. In that sense, it mirrors the human reaction. Again, that points away from a non-violent benevolent society of a workable shared commons.

Are you an expert on bear behavior? How do you know this? How do you explain Bears co-existing nearby while feeding on Salmon without killing one another?

You seem to be absolutely convinced the lens you see reality with is not a lens but reality itself and you are wrong.
