Personally i don't see gambling as a way of escape from the real life issues that you're referring to because any one that uses gambling to evade important matters that is of concern to him is not serious about his personal development and growth, yes it's true that Gambling fun and a fun of keeping your self busy to while away time but should not be confused as an escape rought for one to confront the issues and challenges that life throws at us.
I respect your opinion, this case is just like that of alcohol, people claim they use it to overcome some kinds of situations. Well, in both, I've seen people condemning their efficacies just like you do now, but in the end, according to my personal experience, they both work, though it may not be in every situation and may not work for everybody.
Both gaming (not gambling, but it would serve the same purpose if it's with a physical bookie) and alcohol have helped me overcome relationship issues, boredom and huge financial losses in trading. They have been effective and therapeutic depending on how you view (mindset) and use them.
