In my opinion, perowsnal bans on casinos and gambling will never work, in fact it will make the problem worse, people will look for clandestine places to have fun, also knowing that casino games are for adults, there should be no problem, everyone is responsible for their actions, in that sense, gambling addiction will never be stopped, what a Government that does such a thing can achieve is that everything is ruined and generates more problems than solutions.
I can agree this generates more problems than solutions since most people seek other means to gamble in hiding and serious caution not to be discovered, both the young and old alike. Now the young gets more creative not in productive activities, but secrecy in gambling activities, moreso the chances of regulating their actions are limited since they cannot even own up to be actually gambling.
The country loses also since the casino enjoy their own share of their citizens involvement into gambling since they cannot legally claim the taxes since they banned the casino from functioning in their region while they're actually functioning indirectly.
