Money sure has some interesting psychological traits attached to it.

Let's say I host a video game server and players join

Nothing seems out of the ordinary

But as soon as I create my own monetary system which rewards this fictional currency if a player invests their time in my server

Then suddenly the players have this fictional wallet with the currency controlled by my actions

The players don't think too much about the currency behind the scenes. They just see numbers In their possession and things they want to exchange these numbers for

Daily reminder the economy is fake.
