 Does privacy entail largely unfettered lifestyle choices? Should the state enact health and safety rules designed to save people from poor private choices such as eating sugary, high fat foods, smoking and refusing to wear motorcycle helmets? Are individuals entitled to unfettered enjoyment of drinking alcohol, using drugs recreatioally and a medication-free existence? The answer John Stuart Mill gave to such questions in his famous essay On Liberty (1869) was “yes” to the extent that these are self-regarding behaviors that do not harm others. Mill defended liberal tolerance of intoxicants and narcotic drugs on the ground that liberty nets society benefits that are lost when government tells us what to do. A libertarian perspective condemns the “nanny state” that fails to treat citizens like conscientious adults (Harsanyi 2007: 41).
