Spoonfeeding? Oh, you must be talking about getting instant power from getting emotionally disturbed that requires no training and surgery for even more power. Oh, wait! That's Sasuke!
Let's see. How does Naruto get power ups.....
Oh! He trains constantly for an extremely powerful wind jutsu, undergoes a brutal training for SM, has to fight Kurama to get his chakra after years of resisting his control, then trains to control his chakra! Drat, that doesn't sound like spoonfeeding!
Sorry pal. Every ability Naruto has, he trained for. BSM is him fusing the abilities he's earned. I've never noticed you or any Sasuke fan complaining that Sasuke fused his sharingan ability to gain suanoo without any training.
