That's more a fairytale, then the explanation to human history at least. It sounds almost as if feudalism gone, because guys with swords had no banks to keep their heavy yellowish coins. Which is not very accurate. FWIW very few feudal families were able to hoard gold, or jewels, and for the most part they kept the same things in their castles a village granddaddy would, just in bigger quantities (i.e. food, and fuel). Coins were as expendable as a sauerkraut, and sausages, just easier to store (but not always as liquid as fantasy series makes us think). Were you a feudal you would care the most for the sole thing able to give you wealth almost every year - land.
