I think the point is honey is known as a home remedy, may already be in your house and is available at a much lower price (farmer’s markets and woo merchants possibly excepted).
Honey is also well established in medicine, especially in wound and infection management. I'm not sure of how much clinical evidence supports cough suppression, but it not huge leap to suspect that it could be a second order effect of its antibacterial properties, like in bacterial bronchitis.
