Most of these sellers aren't bad people is the point I'm trying to make. In a lot of cases, they've actually helped people enjoy the game more because they were able to supply amiibos to interested players when Nintendo was not doing so.
If one wants to label that as rationalizing, that's fine, but I don't personally think people should feel bad about spending a few bucks on some fake amiibos for Animal Crossing. This game is meant to bring people to joy and most people are just trying to enjoy the game.
