If that's the case, then I'm sure they'd take steps to ensure they don't have access to cash.
I am not sure if I understand you here.
But if someone wants to stop gambling he must have access to cash but he can not gamble it away. This is why it is so hard to achieve. If a gambler has no access to cash, he can not gamble it away but he will once he has the access.
The determination to change (any)things must be really real, not some hide and seek game.
If you talk to God, you are praying; If God talks to you, you have schizophrenia.
