Since I am not gambling to double my funds, even if I have such money, I will continue gambling because I am using it to entertain myself. Gambling is like a hobby to some people and they don't care if they are rich or not. As long as you are gambling responsible, it's fine.
I think you missed the point. If you have infinite money, you wouldn't be feeling anything, so no entertainment.
I think you missed the point too, because you cannot stay idle and not entertain yourself when you have the money to do so. Are you trying to say that wealthy people don't go to the beach, travel on vacation and have fun. It's when I am very rich that I will enjoy myself the more because whatever amount of money that I spend wouldn't affect my wealth. As long as you are alive, having fun is very important for a healthy lifestyle.
