Earth’s crust too thin to be shown to scale?? Baloney…

Came across this quote in an introductory text recently, “The crust is so thin it would be impossible to see it any whole-Earth drawing shown to scale.” As an inhabitant of the crust, and crustal geologist I respectfully disagree. Below is a drawing with a typical crustal thickness of 25 km shown at scale by the thickness of the black line.
