It is also totally wrong. I got to the third block and quit, as this is just an LLM bullshit version of the 18th century bullshit fantasy of the origin of money (see David Graeber's Debt).

You can't describe how various forms of monetary value work in the modern monetary system as if it were a rural village with physical items, because it is fundamentally different.

It introduced vocabulary well enough though? I get that the specifics were all apocryphal.
