Great example, makes the contrast even more obvious. Insane people are controlling the world, and we are wondering why it’s going to shit

It's a bad example, because we are not monkeys, we lack zookeepers and money normally rots only at a much, much slower rate than oranges and increases itself over a certain threshold

If the monkey traded the oranges to other monkeys for other treats, or for something intangible like status or privacy, the zookeepers would think it was a cool and smart monkey, but they would think the other monkeys who took the extra oranges in trade and let them rot were less intelligent.

But you could do lots of useful things with a billion pokemon cards - either bartering them for goods and services or converting them to money first, effectively "spending" the cards on useful things.

But practicality isn't the issue when people see someone hoarding incredible amounts of something - it's the abnormality of devoting yourself to accumulating vastly more than what we interpret as anywhere near normal. We treat hobby objects that way but not money.
