Harari discusses the powerful narrative of money, demonstrating its role as a shared fiction that societies collectively agree upon. Money, whether in the form of coins, paper, or digital figures, has no intrinsic value; its worth is derived entirely from the collective stories we tell about its value and its utility in exchange. Harari argues that these stories enable unprecedented levels of cooperation among large groups of humans. This example vividly shows how narratives are not just stories but foundational elements that can dictate economic structures, influence cultural norms, and shape human civilization itself.
