Similarly, you aren’t the only one that gets to use your car. Assuming you have friends, they might like a lift from you and not risk their lives doing so because you choose FREEDOM! over seat belts. Or the friends of your kid that you drive to soccer practice. Their mums and dads would like the freedom to have their kids reach adulthood.
We live in a society. We’re not Doctor Manhattan floating above the surface of Mars in perfect solipsistic isolation. It’s not about the government. It’s about your friends, family, neighbours, and community… all of whom are represented by the government.
That’s a legitimate question. Does it need malicious intent otherwise it’s up to everyone to protect themselves from others and no one has a responsibility to mitigate harm?
Also public services are inherently shared services. The delay time and tax payer expense to individuals to have public employees to remove the dead bodies and broken windshields of folks who didn't wear seatbelts on the freeway is an imposition on the shared enjoyment of the freeway and on tax payer income.
Likewise even assuming every injury were treatable, every person getting their thumb reattached or whatever because of a preventable injury means a doctor's time isn't available to treat other injuries that couldn't be prevented. uninsured individuals with these injuries also increase the cost of insurance (one of multiple reasons why our medical costs in the US are higher per capita). Nor is every injury treatable to that extent.
Bet setting that aside, if you really want the freedom to cut off your own fingers accidentally, I bet all the dangerous tablesaws that currently exist will become available at garage sales or whatever very cheaply, so the frugal consumer still wins.
Arguably gives a whole new meaning to five finger discount.
