The government is aimed at collecting taxes, and I think gambling brings them significant revenue, just like the sale of alcohol, so they will not restrict what generates money. Combining alcohol with gambling is the responsibility of the players, if it does not affect their ability to control themselves, then it is fine, but if it reduces concentration and interferes with decision-making, it is better not to do it.
Agreed, the government aren't supposed to be babysitting anyone, it's their responsibility to be gambling with knowing their limits and avoiding things that'll make them get out of control. We're responsible for our actions hence we shouldn't drink and be gambling when we know we have some drinking problems. Imagine combining things that you're having problem controlling. You're supposed to be a responsible gambler because it helps you manage your finances better when you're not under the influence of alcohol but know every decision that you're making. There are people that can gamble and be drinking without being irresponsible, if you aren't like that then you shouldn't be doing that. It's your money and your responsibility not that of the betting company or the government.
