This idea may be absurd, but we never know what the future brings. Gambling is addictive, and yet the government still wants the contribution of the gambling industry.
I think the government are going too far with this cause any process linking to any check of eligibility is totally not fun anymore and probably the energy to gamble may diminish in respec to that. Moreso there are other means to detect for an addicted gamblers other than making some sorts of evaluation that won't yield results. Perhaps the government decisions may limits the addiction rate but in a slow pace manner.
For casinos, I don't think they will go to that extent because as much as possible, they want more players. Because it means, less revenue if they will be very strict with their players. So they won't scrutinize much about the requirements. The government may go to that route, but casinos, I don't think that action will favor their business. For most of them, it is more than enough that you give valid IDs and their own system will detect if there will be some false identities presented. But to go beyond in-depth requirements such as personal details that you usually don't disclose, I don't think they will go to that extent.
Unless, you are in an Islamic country where it is banned to do any gambling act. So the government really had an intervention because they are totally banning such activity.
