I agree this was a waste of time and created even more plot holes, though none of those plot holes are related to the original manga anyway.

The stupidity of the plot can be attributed to the fact of Konohamaru's lack of understanding of what Naruto was trying to teach him and how he thought it was related to the Sexy Jutsu and Naruto being too busy to serve as a proper teacher.
