Well no because in part you yourself fall for the naturalistic fallacy. For a tautology to work it always has to be true. But this is not the case for if it grows there it belongs there(and by extension is not bad for you). For example you could plug in cancer and you would see this equation is not always right. Here is a rather nice website for fallacies https://www.logicallyfallacious.com/logicalfallacies/Appeal-to-Nature
What they want to say is it’s ok because it’s natural but that is the basics of the appeal to nature fallacy
What’s with gospel?
