I think that’s a bit apples to apples; I think a better comparison would be something like a chainsaws.
"The Affordable Care Act's requirement that certain individuals pay a financial penalty for not obtaining health insurance may reasonably be characterized as a tax. Because the Constitution permits such a tax, it is not our role to forbid it, or to pass upon its wisdom or fairness." - John Roberts
Tax Cuts and Jobs Act of 2017 removed the individual mandate.
To the comparison to auto insurance. My question is what percentage of car accidents are fatal compared with guns. Seems to me that personal liability coverage mandates are pretty low <$50,000. So essentially they are more for minor car crashes not to settle vehicular homicide case. In fact if your drunk, or knowingly negligent you lose the coverage. If I burn down my house on purpose, I can't file a claim.
How many non-fatal accidental discharges are there in the US that cause injury? All others would fall out of the scope of insurance anyway so what's the point.
An insurance company is going to over a policy that will pay out my victims if I decide to go on a rampage? Is there anything like that on the market? I'm going to murder you insurance?
