Something doesn't need to be 100% true, in all times and places, to be valuable or essential.
That expectation overlooks the complexity of reality - there may be reasons that Random House, etc. are exceptions, and we just can't explicitly identify and define every complexity. It also can throw away 99% of the value of things. Classical mechanics, in physics, isn't true in all situations, but it's still pretty valuable.
The value to something depends on what we can learn from it, not the flaws we can find, and how well it predicts things. If your expectation is perfection and then the theory doesn't meet it, the problem is with the expectation and not the theory.
