Love (and We) are Nothing but Chemical, Says Some Scientist

But if that batch of chemical called “I” puts a batch of chemical called a “love potion” into another batch of chemicals called “the woman I am seducing” and that batch of chemical undergoes the chemical reaction called “love” that’s “unethical”.

I wonder how complicated a chemical reaction has to be before you can call it “ethical” or “unethical”? Personally, I think the whole attempt to derive “oughts” like “don’t use love potions on people without their knowing it” from “is” such as “You are nothing but very complicated chemistry” is a chump’s game.
