Bitcoin users are supposed to be anonymous, and crypto casino users should be as well.
The main reason for regulating casinos is consumer protection.
I disagree! The main reason for regulating anything by the government is for proper accountability (which includes legal/illegal outflow and
security) and taxation. If the protection of the consumer is the main reason for government regulation in casinos, casinos would fear more than they do. How many customers has the government helped so far?
Do we really want casinos to be used as tools for laundering money, especially when those funds could be used for harmful activities like terrorism?

You made a good point and I've iterated it many times even though some careless people will still argue it with you. Privacy and freedom are good but when they are too much, it causes issues, particularly security issues. I will always vote for regulation even as I do not like many government activities, it still helps limit the damage that total freedom would cause.
