Not only that but I think there’s also a meaningful quality to living in a society with excessive avoidable deaths. I personally think it contributes to a “shields up, guard up” culture that I’ve experienced and found exhausting.
And healthcare insurance if you live in the US, and regardless of where you live it clogs up your entire healthcare system as Jimmy-no-seatbelt flies into the trauma center.
That's an argument against a state-run healthcare system. It gives the state reason to classify arbitrary things as "increases the cost of insurance" and prohibit them.
They could just not cover injuries where a seatbelt isn’t warn.
That said, we have evidence that seatbelt wearing didn’t impact insurance rates. Literally look at the rates over time, even after these laws were enacting, insurance rates rose fast as ever
That's not how emergency room care works. It doesn't matter whether it's covered or not, you're going to get treated; quite likely the hospital ends up eating the bill if insurance doesn't pay.
