To respond to this point I have this to say:
And here's how I see it: I hazard against trying to use this line of thought when talking about Aizen's aura because what that does is open up the door for another train of thought. Simply put, one could argue that Aizen shouldn't have EE in the first place because he's currently given so off of a one-off statement he gives about humans ceasing to be, which could either be EE or, due to the mechanics of bleach, just a mass difference in AP. Like something that hasn't been mentioned is the fact that Aizen's same aura has been noted to turn things into ash, his explanation for what's happening is that human's spirits can't withstand the power, how Soul Reapers in general really do seem to just ignore this aura, especially Gin who just chills next to Aizen with no issue and can even be touched without being erased even though he's well within range of Aizen's Aura. This changes a bit when Thousand-Year Blood War rolls around, but he's also noted to have a dramatic increase in power by then as well so it could still all be down to AP in the end.
Simply put, if people are going to try and argue that the Aizen should resist because one has to be able to survive their own Reiatsu, that makes this sound more like a matter of durability than a matter of resistance.
