Fiat currency has an interesting side effect: it makes you increasingly creative about where to hide your wealth.

Gold in a vault. Art on a wall. Real estate. Collectibles. And apparently, even a banana taped to a wall can become valuable art.

When the currency itself can’t reliably preserve your purchasing power, you start storing wealth in almost anything except the currency.

Quite an achievement: a monetary system that makes people afraid to save in money.
