The gap between the actual theories and the popular conception is what I’m commenting on.
Note that these theories are actually generally descriptive, no one wholesale invented capitalism. For the entirety of human history we have had systems based on a combination of markets, status, family lineage, etc. this applies both to the past and to today.
What I’m taking issue with is the degree to which all of that is glossed over and people assume that the market will evolve naturally if left unspoiled/untouched.
