As you pointed out: " there is a category of people who can be said to be in need of help, there are others who are quite within their right to do with their lives whatever they please". But, if you only provide help to those who need it and are willing to accept it, there would be no forced-treatment-problem like described. I am convinced that quite a few of the "homeless, mentally ill" would be willing to accept help, that they are usually denied (because of the lack of a house, job and insurance).
