I don't think government should set any limit on how Gambler can bet a day. The level one chooses to gamble depends on the person and not something government should interfere. Infact government can not even fo that because they are getting revenue from the lose of gamblers from all this casinos. More loses means more revenue or tax from these casino so I wonder how government will set limit when this is a profitable business for them.
Should this is be good deterrent to at least minimized gambling in a certain country? Or does it force gamblers to uses illegal means or even travel outside of the country that has this strict law to continue with their gambling?
It will not minimize anything, gamblers will somehow find their way out of such gambling limit to a place or country without such restrictions. And this will eventually reduce the profit made by this gambling companies and it will also affect the government from their revenue gotten from this company.
