Natrix Spiritual Cloak Gleam wrote: Stated in mamga and databooks that he completely mastered all jutsus. No. It says he knows all jutsu. He could probably do Hiraishin if he tried hard, but it's fairly clear from Minato and Tobirama that it requires much much more to be useful. The same for other jutsu. Remember that when naruto could split a leaf, he officially had wind release. He couldn't use it practically in any way, but he officially had wind release. The same way, he first used Rasenshuriken yet couldn't use it in any practical way. He couldn't throw it and couldn't hit it reliable, yet he could use it.

Keep in mind that most ninja seem to use maybe 5 jutsu often, and 1-2 jutsu mainly. It's better to have 5 extremely powerful jutsu that you can use very well, than to know 200 average ones. I mean sure you could know Practice Brick for instance, but it's a pretty useless jutsu as a single wall. It's better to invest time and energy into either making a stronger wall (e.g a mud wall), or to invest time and energy into other jutsu that make the Practice Brick jutsu unnecessary.

Power-wise, it makes little sense to spread your training over many jutsu when high-mastery jutsu often need equally high-mastery counters.
