There are three potential purposes of a penal system; to rehabilitate criminals,to act as a deterrent and to protect others. A well designed system can satisfy all three of these purposes at the same time but it requires a well understood set of priorities; and these priorities should be followed consistently. In my opinion the priorities should be to protect others first, to rehabilitate criminals second, and to act as a deterrent third.
With that said, as long as the individual poses no risk to guards or other inmates (meeting the first purpose of a prison system) I would allow them to have quite a few privileges; as long as these are not considered rights. The reason for this is simple, if you take away everything from someone then you have nothing left to be able to control their behaviour; and without this leverage it will be difficult to enforce rules in a highly disciplined environment like a prison.
