Ok, so the dike is leaky, but most of them are small and they have someone who runs around and plugs them. And this is considered an acceptable state of affairs.
No, the dyke could have been leaky if the people in charge of maintaining it did not do routine maintenance and fix things as they came up, improving them as they found better ways of doing it. And then, because it is considered proper, reporting the repairs they have made. Each time a problem is found, it makes the dyke stronger.
Nothing is ever perfect the first time it is made; everything is a work in progress. Or, for you, in your world, would you make something, declare it perfect, and stop looking to improve your product? That must be your attitude with your snide criticism of the "acceptable state of affairs." With that approach, you'd be waiting for ever to get your product out the door, seeking an unattainable state of perfection.
