I would hope that the medicalization is somewhat ironic, but it's hard to tell. Anyway, interest in plants isn't just a hobby. Our alienation from nature maybe has something to do with why it's so easy for a lot of people to be comfortable with poisoning the environment.
Reducing botany to 'a hobby' status is definitely not understanding how important is this science for our interests.
The applications of botany in medicine, sociology, or engineering, for example, are countless.
Or to describe yet another trait of domestication syndrome in humans.
