The Law of Unintended Consequences
The law of unintended consequences surely isn’t universal. Government often seeks to destroy things and truly does succeed in doing just that (alternative medicine, unlicensed professionals, and the like). What it taxes in order to punish, it truly does punish (cigarettes, alcohol, imports that compete with powerful domestic industries). What it regulates to ban, it does often succeed in eventually banning (large-bowl toilets, insecticides that work, effective medicines that the FDA judges too dangerous).
