I think once we start confronting the government with decentralized casinos, which require no KYC, they may decide to loosen up their regulations due to plain redundancy. It would not be fair for such laws to exist, if they are unenforceable in the first place.
Hm, the wide-eyed faith in the power of decentralized casinos to control government. if anything it is just the opposite, governments will find the ways to control them unless their activity will be completely underground one , facilitated by, let's say, TOR network, which, in most cases, is unacceptable for ordinary gamblers.
Regrettably KYC in casinos will be for a long haul , maybe even forever.
