^^ Even if there is a flaw (plot hole, inconsistency of logic, or whatever you want to call it) in this film concerning this subject, it seems that most people aren't really that concerned with it.
Of course not, it's just banter for us Trek geeks.
I do think, however, that this discussion shows the uneasy instability of inserting a walking spoiler alert into the past. As I've noted in another thread, Spock has the EZ-Button answer to every major challenge the Federation will be seeing for the forseeable future. The Doomsday Machine? Doomed. The Horta? Vindicated. The Salt Monster? Desalinized! Etc., etc., etc.
It all comes back to what I said before about the way we fans are so used to rationalizing away the many plot holes that have arisen in Star Trek over the past 45+ years. Rationalizing the inconsistencies and plot holes is what we do...
...We adjust the canon to make it fit what is presented to us on screen.
But if you can easily rationalize ALL plot holes without ANY resistance then the game is too easy. Our game should have successes and failures or there are no stakes.
