That's not really how security works. Either it's broken, or it's not. Security is only as good as the weakest link in the chain. Whether it's good enough or not... hard to say.
That sort of reasoning only applies to algorithms - those shatter the way glass does. Other stuff is more pliable. It's entirely possible to shoplift but there's a nonzero chance you'll get caught. Is the supermarket's security broken? There are many known attacks against it so I'd say that it is.
Notice my wording above - fundamentally broken in multiple ways - by which I mean that there are clear and articulable flaws with the model. Nonetheless it's clearly quite functional in practice.
