Putting that aside, it’s not our role to forcibly limit the choices of healthy, responsible people just because some unhealthy, unresponsible people might make the wrong choices when given the freedom to do so.
It’s not a societal-level tragedy if someone chooses to eliminate themselves. While it’s abhorrent to even consider, the fact is, there’s very likely a net economic/social gain.
We don’t need to be protected from our own choices. We need to be protected from the authoritarian impulses of people who don’t think we’re equipped to make choices in the first place.
