Take the case of motorcycle helmets. Not wearing a helmet increases the risk of traumatic brain injury in a crash. And, people living with TBI get a lot of care at the expense of federal and state taxpayers.

Would a "libertarian" approach to motorcycle helmet requirements deny social security disability income or medicaid to persons injured in a motorcycle crash without a helmet?

Similar questions apply to car-crash injuries without seat belts, and to serious disease in people who refuse vaccines.

At any rate, I do a lot of road bicycling in New Hampshire, always wearing a helmet. Some motorcyclists, legally, don't wear helmets. Enough of those same motorcyclists disrespect other users of the road that it's wise to pull over until they pass.

We don't all live in places with less than 100 people per square mile.
