Most of the time when something does not make much sense on a grand scale such as this, the first thought that comes to mind is that the main protagonist is probably a mentally imbalanced individual. After all. it does take a lot out of someone if they are constantly spouting the same narrative over a long period of time.

In this particular circumstance it might not make sense why he attacks those casinos and still continues to gamble there, however he certainly does not come across as mentally imbalanced. His longevity (with or without possible alt-accounts) demonstrates his determination to attack not only those two but other casinos as and when he can.
