Yes, banking is always mis-used as an example for transactions and ACID but in reality it's eventually consistent, often spanning hours, days, and sometimes weeks. The real-world needs to account for laws, geographies, timezones, physical movement of goods and cash, risk management, etc. that is not modeled in a simplistic database class. I do wish they would pick a different domain to avoid this confusion.
