Ideas are what matter.
It would seem to me that I have the theoretical right, but that I could be legally coerced into treatment, using some rationale akin to that used to justify the law against suicide. Then the message is communicated. The message carefully constructed and brutally delivered is simply a tool of oppression in futile disguise, and is severely distorted in the process of construction and delivery. All of our rights are mere vapors, and yes you can be coerced into undergoing medical treatment. A family member can go to court to have you ruled incompetent and force you into treatment.
