~ It is true that gambling have become modernized, technology have affected and changed almost everything, trying to stop gambling right now will only push people into the older ways gambling was practiced before the internet came into existence.
And also worthy of note is that, every activity in life have their pros and cons, their advantages and disadvantage, gambling in itself is not a bad thing to do, abuse is what lead many people into becoming gambling addicts, those who respect the rules of gambling always enjoy and have fun doing it.
Sorry, I don't understand what do you mean by that? You mean gambling addicts after undergoing a therapy start gambling in land-based casinos? Are there such cases? Because I think it's harder to get rid of internet gambling addiction, and people who are cured from it will not even think of going into land-based casinos.
I totally agree with the second part of your post though. It's not gambling itself that ruins people's lives, it's abusing it is what's bad.
Since the second part is fixed, let me be silent about it, but on the first part, before @Fivestar4everMVP ships in his valuable response, let me say there is a high probability that he is right. I said this because when something happens, you never can tell what the effect will entirely be. Most times too, the effect could be distributed, which is why I believe that he is right and you are also right to have the doubt about it. In gambling, if you look thoughtfully, you would realise that the most addicted nowadays are the ones who are gambling on the internet with their own gadget which is now the closest companion in the 21st century. This is possible because the more they are closer to their gadget, the more they feel that urge to open the app and gamble. This is not the same thing as a gambler who gambles often offline, that alone will limit him automatically.
And part of what will limit him is the proximity of the gambling house to his house or office, even the transport cost is enough to dissuade some people and convince them. This alone could practically help those who are gambling addicts to caution themselves when they vowed not to gamble through the internet again but through the gambling house only. As simple as it is, it will work for so many, though not for all since we have different strengths of mind and determination. Specifically, for someone like me, my yes is my yes, and the same as my no, and when I delete the app, I will not install it again. Under this, it will naturally reduce the gambling extent of the person and this is what I believe @Fivestar4everMVP is trying to point to in the first category. After all, if that could solve an issue that online gambling can't solve, many might resolve to it if need be.
