So my question, are you willing to go to this length for self inclusion because you are afraid that you will want to comeback to a casino and have the feeling of winning the jackpot and then become what others experiencing beginners luck and become addicted in the end?
Very few new gamblers think that way. All I know is that when a new gambler wins a huge jackpot, they will always want to repeat the process because they think they have the knack for it. What a new gambler should be afraid of is becoming addicted, so no, there is no need for self-inclusion, only self-control over how he gambles.
He can still play but should be fully aware of the scourge of beginner's luck. It's up to him how he will behave in gambling, but it's not good for him that he will deprive himself of the pleasure of playing, especially if he started with a good experience.
I agree. It's possible, but not needed
You are always able to self-exclude yourself when needed or in a dire situation, no matter how hard it would be.
