That’s an overlapping but not identical category, I think. Not everything that is a “sin” (violates social norms) is irrational (stupid); not everything that is irrational violates social norms. Lotteries/gambling happen to be both, and so are a bad example of a purely MFFAM policy. The thrust of the original article is closer, but still not quite there: a lot of people do think that racism is just a lack of education as well, so charging rent to racists is both an MFFAM policy and a “sin tax” as well. Something closer would perhaps be... SomethingAwful’s forum registration policy: “It costs $10 to register; we’ll ban you if you’re acting like an idiot; you can come back as many times as you like, but you’ll need to pay another $10 each time.” That’s an MFFAM policy in the small — the money goes to paying the moderators that ban idiots from the forum in the first place, so each $10 a troll pays makes it even more likely they’ll be banned again. And it’s not a “sin tax” — there’s usually nothing perceived as morally wrong with what the troll is doing/saying. (The type of people saying things that are morally wrong in the community’s eyes — talking about child exploitation, for example — get perma-banned instead, I believe.)
