The OP image describes construction with an emphasis on form. Pretty much everyone who uses construction is thinking of the parts as 3d objects, even if they don't draw cross-contours like that.
In the image it's done for the benefit of the audience's understanding, but it's also a common exercise for building a sense of 3d space. When you start being able to "trick" yourself into seeing your drawings as solid 3d objects instead of marks on a flat surface is when that stuff really starts working. This video has a good exercise for that, and the whole channel is worth checking out if you're interested in drawing solids:

That said, I really recommend getting some manner of real life example, even if it's stuff like a box of matches or a mug.
I think everyone likes jumping right into construction because it's important for drawing from imagination and what all their favorite comic and illustration artists use. Most people like drawing random shit they come up with more than sitting there trying to copy their own shoes. That goes for me, too, and it's why I took a long time learning basic shit I never should've struggled with.
Nobody likes listening when they get told to value observation. It's common to end up trying all sorts of stuff before you finally go "shit I wasted so much time I should've just drawn the damn shoes". I don't think the time spent studying more advanced things is actually wasted, because you do need them later on, and I think it helps you integrate what you learn from observation into your own work better. Besides, it's a conclusion you have to reach yourself to be convinced. But drawabox is a total, complete waste of time they're messing with you.
Learn basic comparative measuring from something like Art and Science of Drawing. Observation is the most basic part of drawing and it really pays off, even if you plan on mostly drawing from imagination.
