I think it's fear mongering because it makes people worry whether grocery stores will be able to stay open. As somebody who lives in NYC, I can tell you right now, that if they didn't, it would cause a panic (right now my local grocer won't let people in without masks).
If a panic happened, this could lead people to things like looting. I think looting would be incredibly dangerous, more dangerous than the virus itself. Thus I find it borderline irresponsible to "stoke the fire" by writing an article like this without properly putting necessary disclaimers.
