But hopefully since you don't have to produce a photo ID when you walk into a physical casino in Las Vegas or anywhere else (in the US at least), regulation by governments won't go that far.
I live in the USA and I have to give my ID everytime I enter the casino. I don't know if that's a mandatory thing all over the USA, but where I live it is mandatory. They don't take your ID to tax you on the gambling but to verify your age and possibly check for warrants. You are the 1 responsible for any taxes on your gambling.
