People die because we have liberty. If we take some of that liberty away (but not all of it), less people would die. Less people dying is a good thing, right?
- Take away some or all gun liberty. Less people will die in mass shootings, suicides, etc.
- Take away some or all speech liberty. Less people will die by suicide (esp. LGBTQ youth targeted by hate speech)
- Take away some or all liberty to purchase choking hazards such as Kinder Eggs and less children will die.
Basically, for every cause of death or public health issue, you can almost always limit liberty (in the form of laws, regulations, etc.) to mitigate the issue.
Until we as a people decide liberty is worth a few deaths, it'll be a (slow, because democracy is inefficient) race to the bottom.
