Gambling Hypocrisy

So gambling is so bad for society that government must hold a monopoly as a gambling provider? I guess this is similar to some counties holding a monopoly on liquor sales. Or maybe government could choose to have a monopoly on marijuana sales. The gambling hypocrisy is one of the worst, since cities and states clearly make significant revenues from gambling, but prevent private companies from competing with slots or cards or even other lotteries. The hypocritical state houses should get out of the gambling business and let private companies establish commercial gambling enterprises in accordance with local laws - not state monopolies.
