I agree 100 percent with you that no one should kill over material things.  We were all born with nothing and will eventually die owning nothing.  But as a human species, just like any other animals, we are territorial beings who like to take and claim ownership properties so that we can set our own house rules.  Family = people, land/property/country = house.  Palestinian & Jewish families are always fighting for the same house ownership for example :)  Stay cool & make more videos.
