You got downvoted, but I think this is an interesting idea.

I don't think it is great to be applied as a default to everyone, but if I were forced to go to prison as the person I am today, I would opt for this in a heart beat over being exposed to the general prison population as the risks of that far outweigh spending lots of time alone reading/learning. I know I can do the latter--I don't know that I can do the former and come out unscathed. So for me it all comes down to risk.
