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.

Would I do it? To save a life ,yes. Would it be wrong? Definitely. It's a civil disobedience and someone doing this should be willing to accept the consequences which might include jail or getting shot. It's not ok to steal. Your post is nobel but the thief stealing a TV probably feels like morally he is right too. In this scenario, all would probably understand but it's still wrong.
