This is a tricky question and I am not really sure if the actions would help reduce irresponsible gambling. From the casino side it's a nice way to try and protect their customers. But does losing money and depositing new funds really mean that we are irresponsible? In some cases yes, but in other cases people just don't like to have too much money at the casino. For me it's a security risk to leave large funds at the casino, I would rather pay a bit more in transaction fee and be in full control of coins. From a gamblers point of view an account freeze could help to take a break from gambling and clear our head. Unfortunately there are a large number of different online casinos we can choose from. The gambler can just switch casinos, deposit new money and keep gambling. The only solution would be if all casinos work together and the account freezes is globally. At the moment this doesn't seem very realistic.
