Alcohol is not consumed in moderation though is it. Maybe vouchers for a couple of drinks a week then? Smoking does have upsides - it’s a pleasant experience, in the same way a drink is. I am not a smoker as I have done my own cost benefit analysis but every individual should be entitled to choose.
Ration cakes? Fatties are very expensive to the NHS. Where do you stop.
”people can’t be trusted to make their own choices” sounds very 1984 to me.
