Else, anything can be claimed. Jiraiya uses Rasenshuriken, because he hasn't been shown not to use it. Orochimaru uses FTG. Hiruzen has Wood Release. etc etc etc

It's not impossible for Itachi to awaken PS, had he lived longer. That's not the same as being able to use it. E.g. Minato would've probably mastered Sage Mode and Rasenshuriken eventually as well.
