While I think education matters, I also think at some point if something is purely negative for society one should restrict it, rather than try to reach an ideal state were people are educated enough to handle it right.

It Is illiberal but I don't see an argument beyond the slippery slope one at this point in my life.

Just trying to get normies to understand that slot machines aren't "hot" and "due" for a jackpot because nobody has won recently is virtually impossible. Stats class is hard and people don't really trust what they've learned anyway. A huge portion of the public even believes in such a thing as a person having "good luck". It's nonsensical, tantamount to believing the god of fortune is going to intercede on your behalf, but people really do think this way.
