You're right and I think you could go further. There's a carrot and there's a stick. You can join communities where change happens by force. Think of the guy who runs someone over in his car then becomes a priest to atone. He's not necessarily having fun. Think of slaves: they're not having fun, but the social structure ensures they'll remain slaves. As we speak there are teenage boys fighting each other in the Middle East and Europe - not because it's fun but because their society ensures they'll be thrown in jail or killed if they don't fight.
