You have a bit of a point: things that are fun are much more addictive than things that are hard or boring. And vice versa: addiction makes people believe it is fun. An addict will accept any kind of rationalization before giving up the addiction.
That doesn't mean it should be allowed. Not all fun is healthy. It's been known for over a century that gambling is detrimental, to both society and individual.
