> The way I look at it, let's say 20% of users are addicts and who will jump through any hoop they need to in order to gamble. Very difficult to help this group. Banning won't stop them from betting.

I think this position is fundamentally incorrect. Banning gambling reduces the volume of money in gambling, making it hard to make big bets. You will never stop all gambling, but you can reduce how many people ruin their life with it.
