348. The Bitcoin Standard Course - Lecture 2: Money

— Money solves the problem of moving economic value across time, space, and scale through indirect exchange and media of exchange.

— Barter becomes impractical as economies grow because of the "problem of coincidence of wants"—direct exchange fails when goods, scales, or timing don't align.

— Desirable properties of money derive logically from solving coincidence failures: divisibility and groupability (scale), portability (space), durability (time), and hardness (resistance to supply inflation).

— Hardness—measured by stock-to-flow ratio—is the critical property; easy money whose supply can increase rapidly destroys wealth, while hard money preserves it.

— Money becomes a unit of account once it gains network dominance, allowing efficient price expression and enabling complex capital production and division of labor.

— The "easy money trap" means anything used as money will see production increase until worthless, unless it has high stock-to-flow ratio; hard money therefore wins through economic reality, not choice.

— When evaluating any asset as a store of value or medium of exchange, assess its stock-to-flow ratio; low ratio signals wealth destruction risk if adopted widely, while high ratio signals durability.

— Understand that monetary competition is not democratic—wealth gravitates to the hardest money regardless of preferences, so holding easy money exposes you to inevitable debasement.

— Money's network effects create winner-take-all dynamics; the most liquid, hardest money attracts more users, which increases its liquidity further, so positioning in the hardest available asset compounds advantage over time.
