In a perfect world all money would be money to play with, hence the term "play money." And everyone would always have what they need and want.
But, seriously, do the creators of play money really think someone is going to try to pass off this tiny, grey money, as real money? If yes, who on Earth do they think would buy it?
This sounds like the work of government regulation.
I can hear the play money creators now, "but honest we're not counterfeiters, this money is for kids."
"Yeah, right," say the Feds. "Money for kids to buy drugs. Now get in the car, before someone gets hurt!"
