Arsenic is an essential micronutrient with a toxicity profile similar to selenium (another essential micronutrient). Arsenic is sufficiently available in diets around the world that deficiency isn’t going to be a thing unless you go out of your way to aggressively remove it from the water supply.
Your attempt at an analogy was clumsy and nonsensical regardless. They aren’t serving poison at schools. Sugar would have been a better example.
My point is to think about risk as a scale. There's no need to be pedantic about the analogy.
Would you send your child to school if there was a 1% chance that they would be served something that would put them in the ER? .5% chance?
If you were a school administrator, would you serve food that could put 3% of the student body in the ER? 6%?
