The anonymity benefit will only last as long as it remains deregulated. As soon as BTC casinos become mainstream there’ll be a push to regulate the entire gambling industry and apply similar rules/laws to those that apply to online and in-person FIAT casinos. As you said, it’s usually a matter of red tape. Just because there’s no red tape there now, there’s nothing to say that it won’t be demanded of soon.
That's it. When the demand for this system increases, for sure kyc will follow as FIAT gambling houses required this, and mostly,government will also pushed these requirements even in crypto gambling. It's somehow similar how trading websites are now asking for it coming from their users. The sooner that crypto gambling dominates or gain more attentions, it will be questioned by government bodies who have jurisdictions from the said crypto gambling house.

KYC wont follow the gambling sites in countries where gambling is illegal. People still gamble with crypto there and will for a long time, the TOR network is used more as well.
Countries with regulated gambling, that have high taxes on players winnings, will also be open season for crypto because privacy coins like monero are already accepted by online gambling sites.
The issue for players is trust of the site offering the games, which many of the provably fair games are trying to solve.

This is why Binance moved their company. They would have had to KYC customers (who would all leave) and moving to Malta allows them to keep anonymous trading open for under certain amounts.
KYC DOESNT ACTUALLY SOLVE ANYTHING. The databases for banks and governments are hacked because people are forced to provide their personal information to them. People need to learn to store their own data and not give it out to anyone if they want it secured.
