It is interesting that the author had to portray a hypothetical scenario of learning music theory and never practising to get his point (which I more or less agree with) across.

Sometimes, it is necessary to create unrealistic scenarios and problems because real world problems may be too complicated for beginners. So you end up oversimplifying. In this process, sometimes the essence of the material is lost.

A solution is to pay equal attention to the problem sets and examples as the rest of the course content.
