In the future, KYC will become universal standard on centralized platforms. Governments enforce the laws then companies have to obey local laws if they don't shift their companies to other nations.
So far the government has enforced this rule in several countries for exchange platform. When the owner does not comply with the applicable rule, the site will be banned from operating in that country and may be blocked by the government. But I don't know whether for countries that legalize gambling whether KYC rule have been applied or not, but I believe the rule have something to do with tax rule.
Nations on Earth will become quite strict with KYC and it will become an universal requirement, then companies will have no or little nations to shift theirs.
I'm sure there are other interest from the rule that are made and one of them is taxes.
