Where you pulled this out? All ninjas at the academy do formally train taijutsu, he may never had more advanced or specialized training, like Rock Lee or Neji. By the end of the series, his Taijutsu was considered on par with Sasuke's according to the databooks.
There's a lot of potential for Bolt, true, but gentle fist with Byakugan is efficient because you literally disable your opponent's ninjutsu. You can close in with a light palm strike because of that assurance. If you don't have that assurance (no Byakugan), then doing the same is more dangerous because your opponent can make a counterattack using ninjutsu. Even if you hit their vital organs, they might still be able to launch some jutsu before they fall, especially if you don't hit exactly the right spot.
I don't think he'll master it, unless chakra nodes are at specific points of the body no matter whose body.
If the new spoilers and the scans of the one shot are true, Himawari has the Byakugan, so Bolt could have it too.
As far as I understood, with Kishi's mistake in drawing the white eyes on the 700 chapter, the plot device he created for Naruto's children is that they have to awaken Byakugan and it seems that at the actual state of affairs is that Himawari already awakened hers and Bold didn't, but given Kishimoto's preference for doujutsu characters, I really doubt Bolt would not get it sooner ou later, he just likes too much to make over the top characters.
Other than anger a lot of fans... What good would killing Naruto do for the franchise and story?
Toriyama managed to kill off his own protagonist, Goku. Unlike the Naruto-verse, however, the DBZ-verse showed characters in the afterlife frequently, so they didn't feel quite so "dead." If Kishi kills off Naruto, it won't be like that.
Is there really a reason to think Naruto would stay dead if he did actually die? Kishi brought back a ton of people with Edo Tensei. Far more than was actually needed or necessary. Both Oro and Kabuto are still alive and while Kabuto seems somewhat reformed, Oro is still clearly into experiments and apparently doing it in some legal way considering how Sasuke and Naruto interacted with him. Oro obviously wouldn't pass up a chance to get his hands on his very own Rikudo type breed. We even saw Haguromo appear and bring back souls from the dead to give him chakra and we certainly can't forget that Sasuke has a rinnegan as well. Tbh, there are quite a number of options here so if Naruto does actually die, pretty sure he wouldn't stay dead. Not like Kishi would ever attempt that though.
It could swing either way. I'm not claiming to predict anything. It could be as you say. If I had to think of reasons that Naruto would stay dead, I would recall how every character important to Naruto wasn't brought back often, if ever. Minato came back a few times, through visions or edo tensei. We saw Kushina once. We never saw Jiraiya. The more emotionally meaningful the character is, the less likely it is that they'll come back.
