Alcohol causes cancer, should we reenact prohibition? Water is poisonous in large enough doses. Should we ban water?
Nothing in this world is truly free of all risk. We have to make judgement calls with every single substance. Yes, coloring food is a legitimate use with real benefits that we need to weigh against the risks. And we also need to consider the very real costs of enforcement and burden of compliance. Bans are an extreme option that does not come without costs for the government and society.
Obviously the problem is that Red no3 is so prevalent and completely unregulated. Alcohol is sold separately and ID is needed to purchase and isn't added to children's food. If the dye was only sold separately in bottles this debate wouldn't be happening.
The water thing is even more unserious so I'll ignore it.
