Can't the state regulate driving privledges such as who gets a license, rules and laws to make driving legal. I'm not for laws taking away my rights but I would think safety is a concern. If gov't can't regulate my freedom, then why don't I have the freedom to litter or such..It wouldn't hurt anyone if I did......I just think the principle of pure freedom like pure communism just can't be the end all of an ordered society.........IMO
It's proper that the government raise an armed force to defend the citizens against agression from a foreign government.
Aside from the logical reach someone has already brought up here, that you might injure an innocent bystander if your body is ejected from your vehicle, you pose no hazard to anyone by opting not to wear a seat belt. That issue is what determines if this is an appropriate area for government involvement.
I think you are confusing liberty with freedom. The state can resrict liberty when it interferes with the liberty of others. I have the freedom to swing my fists and long as they don't strike another person. The state has the right to regulate your driving to protect the safety of others in the public at large, but does not have the right to impose a seatbelt law that only protects the safety of the actor.
