The bucket is clearly still functional enough to be used, otherwise the other bucket would be difficult to carry due to lack of a counterweight. Of course the metaphor doesn’t work when you distort it as you have — the flowers clearly are meant to represent something unexpected and positive that arises from a minor fault in an item. If the person in the comic had a wife who was allergic to flowers, then the minor flaw would be recontextualised as a major flaw, and in that scenario, it would be the silly person at fault for continuing to use a functionally dangerous tool.
