> In most (all?) societies that I am aware of you can forfeit your right to personal autonomy and/or life by committing a crime.
Criminals still have rights, some specifically regarding the criminal justice system. Society has agreed after a conviction to not allow criminals to exercise some of their rights to protect the rights of their victims. For example, in order to protect others' right to life we have decided to infringe a murderer's right to liberty.

No, my argument is that even when imprisoned criminals' rights don't go anywhere. Society has decided it's better to violate criminals' rights to prevent the infringement of innocents' rights.
Is your argument that we should not punish crimes with imprisonment or is it that people do not have a right to personal autonomy?
