Roleplayers need no rules.
If someone tells you that you are not roleplaying correctly, you tell them to shove it. Over the last 10 years of online gaming I have learned that even logging into a game is an exercise in roleplay. They are not called “mmoRPG’s” for nothing.
But, as someone that has made rules for himself, (called my Immersion project , now called my Station Project to represent the Station Access games) I can tell you that rules are handy, but never something to obey no matter what. I made my rules to help me feel more connected to my character, not to give me less options. They were made to make my real life feel something like my characters life, and vice-versa, and the rules have nothing to do with other people.
