Does not matter whether the limits are individual or not. If they do not let the real gamblers to gamble and lose even the money they do not have, the industry is over.
They will not be able to pay even employees. At least on regulated markets they do not have to pay affiliates, because they stole everything.
Either the limits will be circumvented with cooperation of operators or it is a game over. If my top 5% players can not play as they played until now even I am not making money to cover my costs (which are pretty minimal btw, few employees and servers).
The problem is not that it is a nanny state. Everything is a nanny state. This is less sustainable than ESG (and it comes from the same think-tank). It is obvious that this industry can work like until now. That everyone will ignore how destructive it is to people. Once gambling industry starts to take seriously the attempts to restrict a problem gambling, it is the game over. I do not care. I am just curious how it will play out.
