If we're willing to regulate gambling (which we are, because we do regulate it), then I don't think we can simply wave our hands at mobile games and say "bah, consumer choice. They play the games, don't they?"
Gambling ruined games like porn ruined movies -- it didn't. It's just a different partially similar thing.
Same deal with games, many previously good IPs are now stuffed with gambling mechanics as the producers controlling it push for it.
I too dislike gambling elements in computer games. I simply choose not to buy such games. If there was a shortage of good games without gambling mechanics, I could see your point. But clearly there's not.
