I was disappointed this wasn't about how money itself works - instead it's about various financial arrangements you can use to scam people.

There's a lot of stuff to talk about with how money works! Like, when I use my Visa card issued by a New Zealand branch of an Australian bank to buy something in Europe, there are zillions of moving parts there.

The fact that money doesn't actually move internationally but yet appears to, and the fact that currency exchange can be done despite that. And that 60% of everything is backed by US dollars (rapidly dropping now). How bank transfers work with and without a common central bank; the different mechanisms countries set up to streamline them.

And, the fact that it's not really centrally controlled, and anyone (like Satoshi Nakamoto) can make a currency and there's not really anything a government can do to prevent currencies it doesn't like, and despite that we do mostly have one government-issued currency per country.
