Come on, you don't think you can be happy without money? Tell that to the people who live in slums. Being happy is not to do with what you have, it's how you perceive what you have. Just like bitcoin's worth is only defined by the value people assign to it.
Are people in slums generally happier than people with appartement/house, car etc.? I don't think so. Also not having a job makes unhappy, I guess most people in slums don't have a job.
