"Organic means better" is the embarrassing and misleading talking point here though, not being against having toxic chemicals in our food sold as "organic". I don't want added copper compounds and residue in my food, and copper sulfate used in organic farming empirically does that.

Your own reference says:

I see a theoretical risk but not a practical problem here. At best you've identified a place where the regulations might need tightening.

This doesn't say that conventional cultures are better on that front.
