Aside from the "ban/don't ban" dichotomy, I think the other option is to basically add some legal friction to doing something to the point where those who really want to partake still can, but its difficult to the point where a lot of people who might otherwise participate don't bother. I take this as the main point of the article, its not that sport betting was impossible previously, but you used to have to travel to a casino or sign up for sketchy, illegal web sites.
Now there's almost no friction. You can place bets just by clicking on your phone, and not only that, there's now a ton of ads and other media reminding you that you can do so. Its pretty clear that this change has caused a huge increase in the harm done by gambling, so even if we don't want to straight up ban it, it seems worthwile to impliment at least some of the limitations that article suggests
