So basically Kishimoto is a puppet and he got to decide shit about his own series. I thought that the manga was good until after the Pain arc (where one editor left), but seeing that even that editor was an influential idiot makes me dislike the manga up to the Pain arc as well."

I think Seel's comment from the Kobayashi interview sums it up nicely. Kishimoto just made crap up as he went. If people were to keep pressuring him on technical aspects, he's probably going to tap William Shatner and be like "get a life". I don't think this one can be put to rest with logic. If this disturbs you, don't go search for more on this. Because a hellofalot of stuff in Naruto was made up on the spot, or pressured by his editor to be added. Not that it's wrong, i get why it happens. But "naruto" and "planning" are incompatible.

I think we can confirm as a fact that Naruto doesn't *need* the Biju since he directly received Hagoromo's power and that guy already had the right chakra + the truth seeking balls. Thus, the Biju being a "pseudo-ten tails" isn't necessary since Hagoromo already has "pseudo-tentails" chakra himself. Thematically and symbolically it works, sure. Maybe that was the idea behind it too. But it's not a necessity.

Whether the Biju are used as an amplification, or as a plain utility is debatable. After all, i think having all these special powers and Kekkei Genkai is pretty damn useful (Like Shukaku's sealing), which could also be why Hagoromo summoned the Beasts to Naruto. Or maybe he did it to inform them of his (hagoromo's) decision to trust naruto. Or maybe to make Naruto a meeting ground to keep them in check. Or all of this. Considering who they were up against, Hagoromo might've just done it to try and squeeze as much power into Naruto as possible.

I don't think we can confirm whether Naruto has permanently gotten his Sage mode either: there's plenty of precedence for the gift of chakra being temporary. Even for Sasuke's rinnegan, since Kakashi was able to receive a double Mangekyou by being "possessed" by Obito's chakra, but lost them upon Obito leaving.
