Of course no one wants to be in prison but there are those who break the law and need to serve time inside. Why make a life in prison when you can make one out of it? Have you ever been to prison? I doubt you can make it a good experience at all. You are literally stripped of your freedom and shoved together with other criminals.
This comment just reminded me about the trailer of a Spanish film I saw a couple of weeks ago, about a man who consistently wants to go to jail. It hasn't been released yet, but it is basically the plot is based in the same incendiary idea the OP proposes, and the chaos if people didn't mind going to jail.
Positive thinking is trendy, but being realistic, this is real life, and what the OP suggests only works in fiction.
