Yuval Noah Harari said this quote
“ Fiction isn't bad. It is vital. Without commonly accepted stories about things like money, states or corporations, no complex human society can function. We can't play football unless everyone believes in the same made-up rules, and we can't enjoy the benefits of markets and courts without similar make-believe stories. But the stories are just tools. They should not become our goals or yardsticks. When we forget that they are mere fiction, we lose touch with reality. ”
