Casinos will not stop demanding for KYC even if the government is not making it compulsory anymore. Almost every casino has KYC feature but they don't make it compulsory for their customers until the need for it arise. Even without KYC you can gamble and withdraw your money, only if you disobey any of the casinos rule they will ask you to perform the KYC.
If the government didn't make KYC verification compulsory anymore and other entities e.g. license, gambling providers, partner etc didn't demand the casino to force KYC verification, I believe the casino will stop demanding for KYC.
Asking KYC will reduce people who want to gamble, if they're free everyone will like to gamble on the casino and will make the casino earn more profit.
so I don't care much about kyc documents
