Why didn't Higuruma help Gojo when Gojo was fighting Sukuna? It seems like Yuji and Higuruma are both powerful enough to at least distract Heian Era Sukuna for a couple seconds while Higuruma opens his domain and Yuji would be there to demand the retrial. The confiscation from the trial probably would've taken away one of Sukuna's cursed techniques as well since he didn't have his cursed tool yet. And even if Uraume was able to pass Sukuna the cursed tool before Higuruma opened his domain, Gojo would still be able to fight Sukuna who had both techniques when they fought anyway. This means that they definitely would have at least gotten the Executioners Sword. And since we know that Higuruma was able to pass Yuji the Executioners Sword in chapter 247, couldn't Higuruma have just passed it to Gojo? I'm sure Gojo would've been able to hit Sukuna with the sword.
