These people don't have control over their mental faculties; they aren't competent enough to make a choice for what is best for them in the same way that minors aren't allowed to go truant or to consent to sex with an adult.
If you are all there in the head, by all means live on the streets, stay filthy, don't eat and ignore people, but this man has a brain disease that makes him lose control of his mind.
If he was forcefully taken to the hospital, forcefully given medication, and recovered he would exclaim "Thank you for saving me! I had a disease in my brain that lead me to believe in crazy things: to be paranoid of police and even medical personnel. I spent 2 years on the streets suffering like this with no place I believed could help me, but you cured me."
If I had a mental disorder that made me go crazy--so crazy that it doesn't even enter my mind that I need help--I would hope that my government would restore my sanity (as I am unable to do so).
