True, but there is good and bad ways to use media (educational content done well vs cheap Chinese children’s TV) and we do have age ratings there.
You’re right that cigarettes are universally bad (smokers would argue not, of course, and probably highlight social moments, pauses to reflect etc) but much of my list has good and bad sides. I’m perfectly open to removing cigarettes from the list, but it doesn’t change the validity of the other areas where we regulate minors’ usage.
