I'm too in the same thought process as you guys. There could be some people that might be destroying their lives due to gambling but such stupid people are everywhere. If they are not destroying their lives through gambling, they'll do it with some other ways. It's a natural flow of money that travels from one to other. Restricting it would be against the financial freedom of people. In modern time, government should limit themselves and let the market decide what it wants and what not. They could just regulate it and earn a cut from the profit.
When players understand that they have to make a difference in terms of things that are fun, it must be taken into consideration that all games are for adults, and Starting from the fact that each adult is responsible for their actions, that is when all governments must Disengage , each one sees what is adult and what is convenient for them.
