It's not like Boruto is weak on his own. Him learning Rasengan in mere days and already with Wind Release applied is a main proof (though Minato, who was also deemed a prodigy of his generatio, struggled with it even in adulthood). Boruto just had no faith in his own strengh and thus he resorted to an easy way (Kote). Even Sasuke asknowledged his potential and stated that, unlike him, Boruto has a chance to surpass Naruto.

@Elveonora, a small correction: Shadow Clones are a B-rank jutsu, it's Multiple Shadow Clones Technique which has an A-rank, and it seems Boruto can't perform it due to the lack of chakra reserves.
