Just because people do it does not make it a 'right'. Lots of examples to draw upon.
Rights and the freedom to not exercise them go hand in hand.
Our right to free speech includes the right to keep our mouths shut and not be compelled to state our political position or vote.
Our right of peaceable assembly includes the right to avoid compulsory attendance of rallies.
Our right to silence includes the right to testify.
Our freedom of religion includes the right not to worship.
Our right to petition government doesn't mean we're forced to do so.
Our right to vote doesn't mean that voting is mandatory.
Our right to receive a doctor's care doesn't mean we must go to the doctor.
Etc.
And our right to life includes the right to choose not to live. And our right to receive a physician's advice and assistance doesn't mean we have to do so. That's up to you...the patient chooses.
Unless, of course, you live in a statist tyranny...where the state controls our lives, not us.
