There's no _actual_ mental health help in this system. We just have prisons and quasi-prisons that drug their inmates and bill their insurance. Short of that, the healthiest thing we can do for people is to connect them with support, only move them from situations they want to be removed from, and otherwise let them continue to live their current lives.
The hands-off approach is how we've gotten where we are though. We can't expect people to make sound decisions about their own treatment during a psychotic break. What good is this liberty they're afforded if that means they don't get better and are a risk to themselves or others (wandering into the street to get hit by cars, etc)?
