this arc fails. this arc is far worse than the curry of life and all of naruto's farting and pissing combined.
You are the one that fails, sir. You try so hard to see flaws that you are even creating them, yourself.

If they had removed the post, the geezer would have immediately noticed the trap was discovered. If they had forbidden the use of it, the geezer might have noticed something is amiss, because nobody is suddenly practicing with it anymore. So, the only choice was to make things appear as if nothing had happened: To have the kids train, but not hit the center. Because, once again, if they had hit the center and nothing had happened (the trap was disarmed, in case you somehow failed to notice that), it would have meant the trap had been discovered and tampered with.

Somehow it's sad that a Naruto filler outwitted you, don't you think?
