Memorizing things is somewhat helpful but being able to parrot back answers to questions is not at all the same thing as knowledge, skills, or experience. Memorizing a bunch of facts is an adequate way to fool someone into thinking you have those things. Testing for memorized facts is a good way to misidentify useful skills.
And yet there is still value in facts. For example, learning the ideal gas law in high school has enabled me to understand in my adult life how gases will react when compressed or when released. Yet the ideal gas law is a simple fact that you can memorize in minutes. In this case, memorizing that small fact about physics enabled me to apply it to gain understanding of other situations.
I believe that the same holds true for other facts one might memorize. Yes, the fact may seem like meaningless trivia (and might even be so at times), but in the right situation knowing that fact can help with understanding. You can certainly spend too much time on memorization of facts, but that doesn't mean it has no place either.
A law is an infinite family of facts, it's already several steps up from memorising a concrete fact like the density of oxygen at room temperature and pressure.
