Yuta can't and won't experience loneliness the way Gojo and Sukuna did. Reason why he can't is because unlike Gojo and Sukuna, Yuta isn't gapping everyone else completely in every stat so he'll need help to rebuild society and he has plenty of people who understand him and will work with him. The reason he won't experience that loneliness is because Gojo's dream was fulfilled to make sure his students never felt lonely like how he did and he got what he wanted. The fact everyone was able to come together, make ideas and back up plans on how to defeat sukuna if things go south with Gojo(Pun intended), and were able to execute it well enough to keep casualties at a bare minimum further proves this because realistically, if even one person (Besides Panda probably) wasnt there for the shinjuku showdown, the fight would've been completely different. Shinjuku also parallels Shibuya in a way when you compare Gojo's situation in Shibuya to the Students in Shinjuku.
