Yes, it's true that there are lonely people who nobody cares about, who don't have loved ones who are effectively blackmailed in to becoming nurses and carers for them after they self-harm. Some of those people are also contributing enough to cover their medical expenses and maybe they exist in a society where somehow they aren't taking medical resources away from equally or more deserving others. On the other hand, however, a lot of people exist as parts of families and communities. They don't need to be mandated not to harm themselves in acts of sheer stupidity because they think about the consequences of their own actions and would be mortified to imagine themselves in a situation where medical resources are being expended on them for no other reason than their own narcissism. But more to the point, at times the task of a democracy boils down to deciding which of these two sorts of personality the society should be geared towards supporting or whether it makes sense to limit the amount of damage that lunatics and sociopths and can do to themselves or to the rest of us for that matter.
