Same needs to happen in the US with our sports leagues. Then we need to make it something you can only do while physically present at a sports book. I feel so sorry for the recovering gambling addicts who want to watch a game these days. You hit rock bottom, you put in the work, you start to pick yourself back up, and some d-bag starts blasting ads for gambling on your phone at every opportunity.
You're asking the US to do what is un-American. American culture is deeply individualistic. From a cultural perspective, a person who fails in their recovery from addiction is seen, ultimately, as being responsible for their failure. They'd typically be criticized for being weak and undisciplined, even if the fake kindness of American culture prevents most people from saying that out loud.
Americas have had no problem with blue laws historically [1], which are laws about what can be done on Sunday largely connected to religious observations, as well as laws on "vice" and entire vice police [2] organizations.
It is no contradiction of individualism, and arguably a strong expression of it, to ensure that anything that can diminish individualism or directly attacks it also needs to be regulated. Heavy drugs, gambling, loot boxes, there's a whole variety of things that humanity has learned the hard way have a tendency to enslave those who indulge in them, and legally banning or constraining those things is perfectly in line with a philosophy of legal empowerment of the individual.
We also have a loooot of ways that people having problems with addictions can reach out for help. There is some truth to the idea that we have moved in the direction of being less willing to force that help on people, and some criticisms to be made there, but then, there were historically reasons for that shift as well that need to be incorporated into any holistic opinion of the situation.
