I agree with everything you said, but my point is that if they use a lie to justify the regulation, they can modify the lie to justify anything. Maybe Goya uses a specific dye that is important to their profits, so they make a donation and they get a special exception.

Remember the scene in A Knight’s Tale where the Prince is like “I looked it up and this guy is legally a knight because I’m the prince and I said so.” Ok, we’re all cool with that because we want William to be a knight, and we think chivalry and honor should matter more than lineage. That squares with our moral code, but it violates the legal system they had established for the movie. It’s a problem, because next the prince could be like “And also in my research, I found an old law that requires I sleep with all your wives.”

If RFK can ban dyes because blue makes kids hyper, next he can ban msg because chinese food makes him feel bloated, or he can ban vaccines because thiomersal causes autism. When the “because” is bullshit, it’s bad whether we like the outcome or not.
