The whole video is just capitalism == money and buying a banana with money is easier than buying it with the products of your labor. Which again just comes off as incredibly uninformed because that whole argument is addressed and picked apart in the first chapter of Capital.

Also the second chapter is Marx’s comparison of barter (incidental direct exchange of goods) with commodity exchange (generalized exchange mediated by money) and says the distinction between these forms of exchange is intrinsically related to the separation of exchange value and use value. But exchange is either absent or a secondary aspect in societies with ownership in common (e.g. past communal societies but importantly also future communist societies of which this woman has no theoretical knowledge):

”Objects in themselves are external to man, and consequently alienable by him. In order that this alienation may be reciprocal, it is only necessary for men, by a tacit understanding, to treat each other as private owners of those alienable objects, and by implication as independent individuals. But such a state of reciprocal independence has no existence in a primitive society based on property in common, whether such a society takes the form of a patriarchal family, an ancient Indian community, or a Peruvian Inca State.”
