Granted. I explode. It doesn't harm you, your family, or your stuff. However, I'm a genie, so I can come back whenever I want, and the explosion hurts basically the whole world that isn't what you specified. Now you're stuck with only what you presently have, dwindling resources, and you're stuck on a small, broken shard of a planet that holds you, your family, and your stuff. Hey, you didn't get hurt by the explosion! I wish I didn't explode...
