What do we know so far, Asuna is indeed a lost cause, this whole idea of Kirito having any chance to fight back it's just wishful thinking. Fujino let the Asuna's plot development roadmap (perks list) inside his code for everyone to see for a reason, and if that wasn't enough, he kinda "confirmed" there will be 2 endings, Oblivious Cuck and Happy Cuck, very similar to his past games... but things indeed have change and this game it's different.
From a narrative perspective i never undestood why he did that, why spoil the end before the beginning?
Maybe and this is only a maybe, our story POV is based upon a unreliable narrator which is Kirito, he dosen't know half of what is going on, have his mind being messed around all the time, most of his time he is linked to a simulation FOG what if nothing what he sees is real including IRL events everything is based on a game simulation.
Fujino could be using in Kirito what happened with Asuna in Canon, when she couldn't logoff from SAO to Alfheim, that could explain a lot of weird things like how the Admin have any influence IRL being only a "digital entity", why several characters during the game say the same thing to Kirito, he need to logoof or spend less time in the FOG and things in this sense.
The only difference would be he's not knowing this is a simulation, made by someone for any reason.
Since we already have 2 cuck endings Fujino could use that to give a third ending like Kirito waking up and realizing that was just a simulation and nothing was real.
