 In nature, for biological adaptation to culminate in better-adapted populations over time, the niche to which a population is adapting must be relatively stable. Likewise, under a rule of law, the aim of government is not to win but to provide a stable ecological niche that enables the game’s true players to evolve strategies apt for success within that niche. An elaborate crystal structure cannot form unless the medium in which crystals form is left undisturbed. Hayek’s ideal is a legal “medium” of society, liberal enough to permit creativity, stable enough to reward creativity, and constraining enough (in the right ways) to steer creativity away from zero-sum and negative-sum games and toward positive-sum games: that is, wealth creation, not wealth capture.
