There's a line where what you call "people's issues with financial self-control" becomes a societal/systemic problem. Alcohol and gambling are the classic examples where extra taxation and regulation like age restrictions come into play. Where is that line for general advertising? I don't know. But it's out there.

P.S. Speaking of videogames, I'm of the opinion that many mobile "gatcha" games should be regulated like gambling products. Hoping legislation catches up in this regard.
