Capitalism in it's true form was "I give you this, you give me that"
So you believe capitalism existed all the way back during the neolithic and beyond, were cavemen "true capitalists"? Capital isn't a set of goods simply traded between people, it's circulating money tied to productive property or alienated assets
Primitive exchange of goods requires the goods becoming the means and the ends even if money is an intermediary, under capitalism it's capital (i.e. money) that becomes the end, while goods may or may not be the means of generation, and since money is the sole metric of success there must a set of people who work for capitalists to create that money and reproduce themselves, since goods are hidden behind said money
