Yes. That is exactly the point. The opposite of nannying is the dignity of risk. Sometimes that risk is going to carry harm or even death. I don't think anyone who is arguing against nannying in this way would bat an eye at the potential cost of lives, that's a feature not a bug.

Constraints on individual liberty as it harms or restricts the liberty of others makes sense. It becomes nannying is when it restricts your liberty for your own good. it should be illegal to drive while drunk because you will crash into someone else and hurt them, but seatbelt laws are nannying because the only person you're going to hurt is yourself. And to get out ahead of it, if your response to this is some tortured logic about how without a seatbelt you might fly out of the car or some shit like that you're missing the point entirely.

That’s a pretty limited take on “hurt”. A person without a seatbelt will get worse injuries, and require greater medical attention. In other words, it does hurt other people.

This is exactly the kind of tortured logic I was talking about. By going this route you're actually agreeing with me and then doing whatever mental gymnastics necessary to twist everything that only harms the individual into some communal harm. Your argument applies equally to riding a motorcycle.

Obviously eating cheeseburgers should be illegal because you'll put a strain on the medical system when you get hypertension and heart disease.
