It is. If it would be totally banned it would result in an emergence of a black market.
We have the same thing on Hungary, there is one state controlled gambling company that's under heavy regulation (18+ only, full with warning signs against gambling, barely any advertisements, has only a few old-school products like scratch cards)
Sure a black market would be worse, but why not just regulate it. Government shouldn't have an incentive to ensure that gambling exists and remains profitable which they do so long as they're running it. Government shouldn't be directly engaged in the business of any vice for that reason.
To add to the other reply, governments can be pretty good at unoptimizing the user's experience. As opposed to, like, game companies trying to make it really easy and tempting to pay for stuff on your phone, the specific government person in charge of this stuff is (hopefully) not walking home with pockets full of money if they get people to gamble.
If it's something like a police officer whose funding comes from collecting fines, sure, there are really bad incentives there. But if the government casino department isn't eating what it kills then it doesn't seem like a problem.
Because the government is less prone to bouts of greed.
No stockholders who expect infinite profit growth, no CxO with bonuses dependent on increasing revenue, and has public oversight by default: government should be the only entity trusted to directly engage in any vice business. They are the only entity I trust to put honest effort in decreasing their user base.
This view is predicated on whether you trust your government to do the right thing or not. The government is already trusted with policy and handling opiates, without going Perdue pharma
- criminal org’s major revenue stream (prohibition)
Given those choices, state+ size governments are least likely to paperclip-optimize for gambling “revenue”, and federal/national government would care the most about negative externalities since they compete with other nations, on metrics removed from raw “tax” revenue.
It seems barely any better make a state revenue stream out of it.
