I think Tsunade, remembering everything that was said, realized that Naruto was the child from the prophecy. And only he can resist all this. Plus, after Naruto coolly told her about Jiraiya, she realized that he would definitely not forgive her for this.
@RaisaRomanova: The prophecy did not say that he would always cope with any crap. Perhaps, just the fact that he participates in the battle can destroy the whole world (if he is captured).
From my point of view, when he spoke about Jiraiya, it was about emotions and lack of information, very childish.
But... But if there is a barrier there... Why didn't it work on Orochimaru and the four of sound? Did they know the ANBU seals too? Why does it look like a detail suddenly added to the narrative
