Ok, but I'm not a gambling addict, and most people who gamble don't become addicts.
I know people who are literally homeless because they'd rather spend their money following bands around. Some of those bands are too niche to be "socially valuable". Does that mean we need to equate music with heroin, too?
The existence of addicts, or the lack of a social movement or physical product, does not determine whether something is worthwhile. Applying your standard would cut out everything up to "going for a walk in the woods", unless by socially valuable you just mean "things I find aesthetic".
