That’s pretty much my interpretation, too. The fact that exchange happens so frequently and is part of everyone’s daily lives, combined with the money form obscuring the underlying exchange of commodities, means that people end up treating it somewhat like a law of physics. People live with gravity without knowing what causes it; similarly, they don’t know why a commodity is exchangeable for a certain amount of money and vice versa (beyond what’s taught by bourgeois economists like supply and demand)
