Dans les pas du célèbre "I, Pencil" de Milton Friedman, on lira avec intérêt cet article magistral de l'économiste Don Boudreaux:

If our world were random, it's a virtual certainty that the resulting combination of resources would be useless. Nothing worthwhile would be produced. We'd all starve. Because only a tiny fraction of possible arrangements serves human ends, any arrangement will be useless if it is chosen randomly or with inadequate knowledge of how each and every resource might be productively combined with each other.
