Yes. It is surprisingly a near impossible engineering challenge at the levels Apple hardware is being done. Have you even considered the wear and tear that a mere hole in an ABS plastic molded detail would be subjected to over the lifespan of...several years?

(Just kidding, obviously they just want to upsell their customers with extremely overpriced accessories.)
