But instead of the paper money you are used to seeing on Earth, you notice all transactions are being completed using small seashells.
Curious, you tap an alien on the weird lump you think is its shoulder.
After it processes your strange language, it looks puzzled.
“The ‘seashells’ you belittle are very rare, impossible to produce, come in different sizes, and are durable.”
“Ah, sound money!” you reply.
The market gate swings open and who saunters in? None other than Mr. FEDerico, the man of endless means.
He climbs the tower in the center of the market and clears his throat...
(Seashells, of course, are easy to find on Earth, despite their rarity here).
The market turns into a frenzy - sellers going crazy over the profit potential.
What happens next?
With the massive influx, the value of seashells collapses. Savers are punished as sellers raise prices.
The thriving society collapses. Without sound money, it could not function.
You hop back into your space ship, ready for the long flight home.
“Aliens are wild,” you laugh, “That could never happen on Earth.”
