On the list of hurricane preparations is a first aide kit. You have your meds with you and take them if you leave or keep them close esp if life saving. You stock up on water and food. I have enough not just for mine but for a neighbor that might not have prepared too. That's the way you do it. No need to loot stores and RXs.
Of course you plan ahead and have supplies and medicine. But not everyone is always prepared and excrement does happen.
I was only objecting to the absolute statement that it is always wrong to take without permission. There are cases where I would feel no moral harm in doing such a thing, if necessity necessitated it.
Would you let someone die of anaphylactic shock rather than "steal" from a closed and abandoned pharmacy? I would not. To say it's always wrong is to say that we must let that person die rather than steal necessary medicine. I don't think that is the moral thing to do.
