people like hope. In Dickens era the hope was that you'd discover you were a long lost bastard child of some wealthy aristocratic family. These days, its that you win the lottery.
We shouldn't conflate permitting lotteries which give a lot of people precious hope, with enabling the disease of gambling addiction. Gambling addiction transforms its victims into desperate degenerate messes, who will do anything in order to reverse the outcome of their losses. By popularising gambling on reality (instead of a sandbox like sport) we're creating a future where such people will harass journalists, which further threatens our increasingly precarious relationship with truth.
