I attempted to respond with extending the knife-analogy, but it stops being useful for LLMs pretty quick since (A) the danger is pretty obvious to users and (B) the damage is immediate and detectable.

Instead it's more like lead poisoning. Nobody's saying that you need a permit to purchase and own lead, nor that you must surrender the family pewter or old fishing-sinkers. However we should be doing something when it's being marketed as a Miracle Ingredient via colorful paints and cosmetics and dusts and gases of cheap gasoline.
