What I think is that playing online gambling will make it easier for someone to drain their wallet than a physical casino. As you said playing in front of monitor won't make them play for long, it's because their money has been used up.
When their physical health is saved, it doesn't mean also with mental health after experiencing severe losses in a short time.
What you are saying is true, but only for a certain group of people, namely, for problem gamblers. And I meant the vast majority of people(gamblers) who are not problem gamblers, according to various stats. And yet, I think we have to wait several years before we can make sound conclusions on this matter. Can crypto gambling make the overall health of gamblers better, only time will tell.
Itt may be easier to stop playing but it's also easier to start. Some people have anxieties or are too insecure to go to a crowded casino where everyone watches them and play at a table.
Online gambling gives them a comfort of their own room and the anonymity. There's also no age restriction. They can always lie in an online form when they wouldn't be able to do it in a real casino.
Theoretically can be true, but it's a complex problem with no simple solution. Those kids who gamble online would not necessarily be learning math and biology if there were no online gambling. What is more likely is that they would be taking drugs and robbing people on the streets, because they are wired that way: they are craving for immediate pleasure and profit.
