If in your business it's quite likely that the equivalent of that 'kitchen cabinet' is going to be replaced, or simply become unused, or that you're going to switch to an entirely different house with different cabinets - then it becomes obvious that in those scenarios spending time and effort on bugs like “Loose shelf in kitchen cabinet” may be totally counterproductive. Essentially, it's the YAGNI principle on a bit higher level of abstraction, where the default assumption (and not that unwarranted) is that whole tech systems and/or business processes often are short-lived, disposable and actually disposed of.
