In general I agree with you.
But what if a 4 year old who can't read eats a bagful? Or somebody who can't read english?
Astonishing it is available at all.
I think that "Who reads labels?" definitely applies when the bag contains a lethal dose of cyanide.
Everything has a warning label anymore and most are just to appease lawyers or regulators. Nobody pays attention to them.
