However, I don't this is going to work because and addict who can't control himself will definitely find a way to get more money.
It doesn't work like that, self exclusion is when you contact the casino to make your account off from gambling. It's not about when you lose money and you find a way to make money again to gamble, but when you get yourself self excluded in a casino, you can easily betray yourself because you'll just have to find a new gambling site that will cater you.
Money is not a problem for gamblers, unless broke. This self-exclusion actually is just like fooling ourselves because its real purpose is not realized, that's from my personal point of view.
You seem to be mixing things up here, and if a gambler is not addicted because of the fun, then it must be for the money, so the money is still the problem of the gamblers. Also, you might have misinterpreted what @khaled0111 said there and I think you guys are still saying the same thing after all in the rest. Self-exclusion is just a way to restrict oneself, but not a way to cure gambling addiction. Just like you said, if he self-excluded himself but moved to another casino platform to play, is the issue still not persisting? That is why he said he doesn't think it can work just like you as the gambler may still find more money (even if he followed the style of the main OP) to still continue to gamble.
These are good points and I am certain that since gambling-related issues are psychological, psychological approaches should be used to tackle them as well. Self-deprivation like exclusion and locking out funds may only limit but will never cure the issue.
The main point of my statement is that self-exclusion that is a feature of few casinos out there seemed to be like a negative feature as a gambler could just easily choose to gamble to other casinos once he lock his account and realized the urge is still there. Casinos should only offers more games, and more bonuses that will attract more gamblers and satisfy them, they should not think of any feature that is related or could prevent gambling addiction as their main business is to serve people hence it's already expected that once a gambler opted in, they already understand what responsible gambling is.
If a gambler gets addicted, it's not anymore the business of a casino since it should be taken cared of outside casinos. Remember that casino is a business, their main goal is to generate revenue and will only happen if they could retain loyal gamblers and attract new. Self exclusion is discouraging gamblers to gambler, that will hurt the casino's revenue.
You still repeated the same statement, and at this point, I do not know whose side you are. Is it the casino/business side or the humanitarian side? If you are a concerned person, you will always choose the healed world/humanitarian first over anything else including the business. You are looking at the core goal of casinos and the relationship with the customers, but overlooking the damage it can cause to some people who could be a victim of it. Fine, gambling is an adult activity and people, including the government and casinos expect it to be played by mature and well-prepared people. I have also preached that many times. But at the same time, we are all humans, we can't be wise/smart or think the same way and even some younger people may be more mature in handling themselves and things of life better than some older ones.
Look around you, are people the same? It is not everybody that is smart or can think for themselves or control/restrain themselves in some situations. This is why some external restrictive features like self-exclusion were put in place instead for some gamblers to be wasting their lives and fortunes away due to addiction which they can't control. Do you think that these addicted gamblers would want it for themselves if they were with their senses or able to correct the issue? This is why that feature is important, but the only issue is that it is not so effective, nevertheless, it has helped some people for real.
Now, effective or not, advocating its abolishment is not humane, it shows you do not care about anybody, that's what I was telling you, it's wrong. Who cares about more bonuses and offerings when a life is wasting off due to addiction? The self-exclusion feature is still an effort to help even as the addicts continue to find other lasting solutions to their problems.
