Why can't we just do the same with gambling? Alcohol consumption is extremely risky not only to the person consuming it but to the people around him. There have been so many cases of crimes due to alcohol consumption. Many people's health destroyed. So what makes it ok for alcohol ads to continue in public but not gambling?
Alcohol have health effect to human health, and because of how it take sense from people when consumed much, it is not allowed to be taken in excess in many countries, and you can’t also drive while drunk because of your safety.
We can’t relate this to gambling that you do by choice; you want to make money quickly through gambling, that is why betting is at your own risk.
For restrictions; I think it is not prohibited completely, just doing it physical might have influence in our young generation which is very bad to know about at early age.
