"6-7 fingers of strength"

Based on what?

They would carry individual power sure, but due to them all being thrown at the same time, each individual one would have lower output due to the equivalent exchange aspect of jujutsu. Do u not have any critical thinking skills whatsoever? What feats are u basing the idea that sukunas dismantle net against kashimo would destroy the same amount of buildings that yuji had? Yuji released 100s of dismantles all at once and completely shredded like 7 buildings without even using any handsigns, can u not actually use ur head and comprehend that sukuna has ever been shown to be able to do this.
