agree with first 3 points
Sasuke need to put Naruto in genjutsu in order for CT to work and he can˙t absorb chakra if Naruto isn´t restricted (somehow)
Naruto counters for CT
1. TSB turn stone too dust
2. Kurama tail smash stone (Kurama already broke CT thanks only to tails against Pain)
3 TBB barrage easily destroy them
IF he could Sasuke would trap Naruto but he simply can´t
Genjutsu isn't really needed to trap him in CT (and using genjutsu isn't hard because his rinnegan genjutsu does not require eye contact any way, sure kurama will free him in a few seconds but this will give sasuke more than enough time for a rinne blitz) and Sasuke can absorb chakra from anything inside his CT.
Naruto can free himself with raw power but it'll give sasuke more than enough time to absorb chakra from him while he's inside.
as for your counters:
1- TSB will turn jutsu into dust but the rocks are just normal rocks that were being attracted towards Naruto so he can't turn them to dust (it didn't turn Sakura or hiruzen's shuriken into dust)
2-but he'll still be inside the CT so which would take time for sasuke to absorb
3-That would only work if he's outside the CT.
