Well, ignoring the concerns about government intervention vs individual responsibility, the reality is daily fantasy companies advertise in such a way that it makes it appear anyone can be a winner, when in fact the vast majority of winnings go to the same set of elite players.
That's just flat out false advertising. At least Vegas is up-front about the fact that the odds are in their favour. And I think it's perfectly reasonable to have the government enforce basic standards about advertising and communication by companies to the public.
