Why did Naruto decide not to use the Rasenshuriken due to the harm it did to his arm, if he could create it with clones?

Question

The first time Naruto used the Rasenshuriken, he created 2 of them, one of them created fully with clones as a distraction, and another one created by him and 2 clones. Then, the real Naruto gets injured in his arm due to the technique and he decided after being ordered by Tsunade not to use it anymore (at least for a while). But as it was shown in that battle he can create a Rasenshuriken fully with clones, and the harm the clones get doesnt get transfered to the real Naruto. Then,

In a way, theres two answers. Chronologically, the first one is because he couldn't, or wasn't allowed, and afterwards, there would be no need to.

From the Naruto Wiki on Rasen-Shuriken:

After travelling a certain distance or colliding with a target that it can't slice through, the central sphere of the Rasenshuriken detonates, producing a vortex of wind in the immediate area. Within this vortex, countless microscopic wind blades are created, so many that even the Sharingan can't count them all.The wind blades pierce every cell in the body, disconnecting them from the Chakra circulatory system and so preventing them from providing their physical energy to the chakra-creation process. Because of this, the target loses their ability to create and mould chakra, damage which cannot be healed by medical ninjutsu.Tsunade likens the damage to poison, and warns that if the damage is great enough, those affected by it won't be able to use jutsu again. ^{(emphasis mine)}

Because the jutsu damaged the user itself, Tsunade marked it as forbidden, which is why he wouldn't be able to do that, as I previously mentioned. It was forbidden. So, he wouldn't be able to do this because the jutsu was marked forbidden. Most jutsu, such as the Shadow Clone Technique, are made forbidden because they can severely damage or kill the user. Rasen-Shuriken was an example of that. So of course, he wouldn't do it with a clone. Naruto didn't even have permission to use it.

And as to why there would later be no need:

Naruto is able to overcome these flaws by learning senjutsu. By infusing the Rasenshuriken with senjutsu chakra, its shape is maintained after formation, meaning that he can use it as a projectile and, as a result, that he no longer needs to worry about damaging himself. ^{(emphasis mine)}

So, one he couldn't do that because it was marked forbidden, and later, when he mastered Sage Mode, he wouldn't need to because he himself can throw and maintain its shape upon entering it.

But when Tsunade told him, don't do this because it will harm you, he just could have said, it wont harm me if I create it with clons. Instead, he said, I wont do it anymore because I know it harms me. Doesnt he use clons all the time as decoy for not harming himself? — Pablo, May 31 '21 at 14:38
@daniel because at that point of the story where the question is set he didnt know that. — Pablo, May 31 '21 at 20:18
@daniel . That isnt really what I'm asking. I know Tsunade asked him not to use it because it would harm himself, it's mentioned in the same question. But Naruto always questioned Tsunade decisions and most of the times he got to do what he wanted. In this case, instead of questioning Tsunade, he said he knows the technique makes harm to himself and that's why he wouldnt use it. But he knows he can use the technique without harming himself. Then why didnt he tell Tsunade this? If he would, Tsunade wouldnt care about him using it, since the only reason for her to ban him was not to harm himself — Pablo, May 31 '21 at 23:08

Because this would kill the clone completely, as mentioned in the duplicate comment that @ᴅᴀɴɪᴇʟッ mentioned.

Taken from that post,

The reason that a clone could not work in this scenario would be due to the fact that clones are dispelled once sufficiently high physical damage is inflicted to it. It would be my belief that a clone could never sustain its form long enough to sustain a hit with the Rasenshuriken before it - and the jutsu - were dispelled.

Naruto did not use Rasen-Shuriken with his clones because of the damage that it inflicted to him, which would make the clone dissipate entirely. This would make it unnecessary. But as @ᴅᴀɴɪᴇʟッ mentioned in his own answer, this disadvantage would later be bypassed because he learned how to throw the clone upon gaining access to Sage Mode.

great answer, but could you explain how exactly the damage inflicted on his body still left no time to proceed with the damage? AFAIK, jutsu should do damage the moment they are in contact with someone else — ᴅᴀɴɪᴇʟッ, Sep 27 '21 at 20:05
@ᴅᴀɴɪᴇʟ The damage inflicted to Naruto (and his clones arm, in this hypothetical case) is too great for the jutsu to even inflict damage in the first place. As I mentioned in my answer, the damage inflicted by the *Rasen-Shuriken* would kill the clone because of the damage it inflicts on Naruto's arm. — Tristan -_-, Sep 27 '21 at 20:07

Why did Naruto decide not to use the Rasenshuriken due to the harm it did to his arm, if he could create it with clones?
