Never denied it, I'm saying that, in order to increase productive efficiency, the idea (not the effective institution) of private property emerged in order to specialize work. Say, Grug was the smith of the tribe, a job which required advanced skills even at a primitive level, since he had the most experience. Naturally at one point, maybe after several smiths are present, Grug's forge stops being &quot;the forge&quot; and becomes &quot;Grug's forge&quot;. I believe this was the seed of private property. Also calling hunting grounds &quot;means of production&quot; is not entirely accurate.
