We require seat belts because we've decided that our society is better when we have fewer people dying in car accidents. The disruption & trauma to their loved ones (and other driver), plus the loss of life, are perceived as worse than the inconvenience of wearing a seat belt. Similarly, we could decide that the personal freedom to become addicted to gambling is less important than the potential impact to that person or loved ones. All laws are about restricting freedom for the benefit of the larger society. There is also no individual that does not impact their society in some way - a harm to them is (often) also a harm to others.
