while i dont follow the logic (what color is your shirt? if you need to imagine other options it means you only have the one?), if i interpret you charitably you might have thought i meant "imaginative" as in not realistic. but i simply meant there are other possibilities. the phrase "failure of imagination" has a somewhat technical definition: it means something obvious in retrospect that most people didnt think about until after a fact. like how it is obvious a plane could be hijacked. if i had to guess, id say the common conception (at least in NA) that there aren't other options to fight this virus is possibly because public knowledge of the pandemic is largely via news/entertainment media (compare for reference any other subject matter).
