The government would have the most problems with this solution because now they cannot rightly justify controlling suicidal people and keep them out of society. They would no longer be able to force them into treatment because there is nothing that can diagnosed as needing treatment. Therefore, the government would no longer be in full control of its citizens' lives. The Court declared this statement in 1891. It means that everyone owns their own body and has the right to do with it what they want without any interference from others.
Suicide is no one else's choice but the person wanting to do it.

It would be so much easier if everyone, meaning the government, would just butt out and give everyone the right to lead his or her own private lives. The Ethics and Politics of Suicide.
