There's literally no reason for Naruto to not learn some basic wind slash jutsu other than Kishimoto not wanting to expand his kit. The Rasenshuriken was a super difficult to learn S rank jutsu that even Minato couldn't master, so learning a basic, B rank wind slash jutsu would have been a cakewalk. He had to slash through an entire waterfall during his training anyways. Also, why couldn't he learn a Wind Clone Jutsu? We know the elements have their own shadow clone variants. They could launch wind slashes when destroyed, like how Kakashi's lightning clones zap their targets
It's a shame that Naruto didn't get along with Lord Shimura, he could have learned some more Wind Style jutsu from him
