As what the question is, Do you think governments should set limits on how much one can gamble daily?
No, I dont think so. This will affect the casino's business. Casino earn big profit from people who gamble with large amounts even if its bit by bit. If they government set a daily limit, those players wont be able to spend the entire money on gambling in one day. And also, even if it was effective, it wont reduce gambling addiction in the country. Addicted highrollers will create as multiple account, making sure they spend the entire money and get satisfied.
In the casino's business side, this is bad. But for the people, the consumer, which the main goal of the government to protect, it's perfect.
Also, the chance of revenue that the government will get from casinos' taxes/fees could decrease because of this, less revenue for casinos could affect the revenue that by government gets from them (not sure about this).
