I'm not understanding your example; as far as I know gypsum/gypsum drywall isn't toxic.

If you let your kid eat drywall compounds, and inhale drywall dust in the process, you’re not only missing my point, you’re proving it.

Just because it isn't toxic doesn't mean it is edible...? I would not allow my child to eat drywall, but neither do I consider drywall toxic. i.e. if they started chewing on some drywall, I wouldn't haul them to the E.R. in a panic.
