Saleability Explains Why Some Goods Become Money
- Saleability measures how easily a good can be sold at its prevalent price and explains why some goods become money.
- Saifedean contrasts $100 bills, Treasury bonds, houses, and gold to show bid-ask spread and liquidity effects.
High Saleability Creates A Winner Take All Money
- The more saleable a good is, the less its marginal utility declines as you accumulate it, creating a self-reinforcing winner-take-all dynamic.
- This explains why one most-saleable good (like gold historically) emerges as the general medium of exchange.
Four Dimensions That Make Money Saleable
- Money's saleability depends on solving four coincidence axes: across goods, space, scale, and time.
- Saifedean links each axis to money properties: general demand, transportability, divisibility/fungibility, and durability.
