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.
