But why does the government have to interfere in people's lives? If someone is addicted to the point of harming their own life, it is a case of medical help and not government decisions, because for an extreme addict it doesn't matter if the government prohibits it, the addict will find a way to continue playing... For me, these decisions by the Brazilian government border on dictatorship and are an excuse to be able to collect money through taxes.
You’re not seeing the big picture here. Think of it as a large-scale problem. If the government lets its citizens get hooked on gambling, it’s only going to create bigger issues for the community - and those issues will eventually come back to haunt the government. Normally, they only ban gambling when addiction gets completely out of hand because they’d rather lose the tax revenue than deal with the fallout of a public health and financial crisis.
I agree with @freedomgo said because if many people gets addicted to gambling, that will gives a big problem for the government. They will difficult to handle the addicted people in gambling and that can also increase a crime as I see that could be related. When someone don't have money to playing gambling, he can commit a crime and that will harm other people. Yes, the government will lose the tax if they ban gambling from their country but that will be their citizens good. The government can finds a way out from getting the tax from the other things. But that will not guarantee for the underground casino because that casino can operate without anyone knows especially if more government officers involved.
Addiction will be there since they still allow casino that will comply to their requirements to operate. They impose ban for those illegal casino that operates in their country. So with these they didn't totally eliminate online gambling on their country and they just want to regulate all of those illegal casino since somehow this could give huge revenue to their country.
Maybe those protection towards addiction is just an excuse, but provably the main intention of those things happen is to get some revenue to online casinos that will comply to the rules they set.
But again for sure, there some ways to continue to participate on this activities and provably some old time gamblers would use some tool to access those online casino and get back to their usual activities.
