Ideally we would look at things analytically. If you've been hit by a car and are unconcious and unable to consent to treatment, you are still treated. It should be that if you are mentally ill and unable to consent to treatment, you should still be treated. If one day I lose my mind and I am on my own on the street, I would hope that I would get taken to treatment rather than be allowed to die on my own.

It's time we put virtue signalling aside when it comes to medical treatment. If someone is experiencing hypothermia and not in the right state of mind, we don't allow them to strip off their clothes in confusion even if that is the natural stress response to hypothermia, we hold them down and get them warm and well. If your friend is drunk and belligerent, you keep them home where they can sober up safely instead of letting them wander into traffic, even if they try and wrestle away. We should do the same for those suffering from mental illness, who due to their illness are in no state to care for their wellbeing, and we should do what we can to treat them until they are in the right state of mind.
