The ideology of the nanny state can perhaps be summarised as coercing people to be healthy. Complaints about the first half of this (coercion) are well known: people should be able to make their own choices even if this involves them opting to smoke or drink or eat sugar. However, most people would regard the second aspect (health) as uncontroversial. Whilst the means of nudging, taxing, banning, and regulating may be objectionable, the end of promoting health is obviously a ‘good thing’.

I’m not so sure that this is true. Obviously, health has its benefits. Most people would prefer to not have typhoid. A healthier population may also be more efficient and happier. And, if you enjoy your life, it’s rational to want it to last and to die at 80 rather than at 40.
