If our brains have a hard time distinguishing between perceptions of reality and imagination, what would make anyone think that currency, or tradeable goods would be any different? Games like Clash of Clans scare the hell out of me already, I can't imagine stumbling into a gambling addiction at 19 years of age...
That is, I think it says more true things (that are more an analogy than an exaggeration) than we're generally able to admit or even process. Our plates are so full that our tiny spoons sometimes strike me as fig leaves rather than eating utensils.
