You do not take into account those players who, for various reasons, cannot de-anonymize their identity and, accordingly, provide the casino with their passport details, including their place of permanent residence.  Also, many people understand that the personal data provided to any site, which is considered confidential information almost all over the world, and access to this data is limited.  So, all this data, when it ends up on a third-party site, for example, a casino, still ends up in the public domain over time.  This happens in a large number of cases due to theft or unauthorized sales of personal data databases.  I would not say that such people should be classified as some kind of second-rate category of players compared to those who are required to provide KYC everywhere. 

So I say that the state is obliged to provide guarantees of quality service for such citizens, and not just those who around the world recklessly and without thinking about the consequences send out their personal data anywhere. 
And this data has already been stolen many times and appears on the darknet or even just on the Internet.
