It wasn't out of habit like you said Yes, I fully agree that I was mistaken in my earlier comment, I had forgotten Naruto's reaction to Kakashi's Rasengan. I was mostly remarking to the other user that Boruto's use of Rasengan at his age without clones was not that much of a leap from what Naruto could do at that age.

It's similar to how some users believed that the Shadow Clone Jutsu was supposedly an advanced technique that was difficult to perform and cited Sarada's use of it in Episode 24 as her being overpowered, even though the Shadow Clone Jutsu was never at all even implied to be difficult to perform.
