Yes.
Agreed.
Agreed.
This is where I am confused, are you saying naruto's chakra has been replaced completely by rikudo chakra? If so then what makes RSM different from the SM you described in the above?
Yes, Naruto's chakra has definitely been replaced by Rikodou chakra. So the Rikodou chakra is basically Naruto's new chakra. This has been proved by Naruto's augmented base mode. If Naruto received Rikodou chakra like an addition as he received bijuus chakra, his base mode wouldn't be enhanced.
It's also a bit confusing to me. Naruto's power ups in general are confusing. So I can make assumptions and basically put everything that should be put into perspective. So it'll indicate my perspective and open up things so you can also put your thought into it.
Firstly, Rikodou chakra possession buffed every single attribute of Naruto. 1) Which means all of his forms including Base Mode, SM, BM and BSM have been empowered. But you can't use the prefix of "Rikodou" for those power upgrades because then we will also have to call Naruto's base mode as "Rikodou Base Mode". 2) Plus, none of the Rikodou enhanced modes have visually changed which means Rikodou enhanced SM is also visually the same, which proves that RSM =/= Rikodou chakra + NE.
Secondly, RSM was called to be a gift from Hagoromo which means not everyone who has Rikodou chakra and SM will be able to achieve it. What they will achieve will be SM enhanced with Rikodou's chakra.
Thirdly, Naruto's eyes in RSM are plus signed, which could mean that in addition to SM (natural energy),
Kurama's chakra is also involved. So if we're looking at as something not exclusively given, but is attained by combining few powers, then it's possible that even non-TSB RSM is attained by combining Rikodou chakra+NE+9 Bijuus chakra. TSB RSM could just be a secondary state, just like how BM's primary state is the cloaked version and the secondary state is the manifestation of the Avatar.
Otherwise, it could be possible that Naruto can use Rikodou's chakra in two different ways. One is for regular power upgrade and one grants a special power. Moreover, if we correspond Naruto's power up to Sasuke's power up, we see that Sasuke gained Yin Rikodou chakra (power source) AND Rinnegan (power to be used with that power source). So Naruto also gained Yang Rikodou chakra (power source) AND RSM (power to be used with that power source). That makes RSM an exclusive power granted
along with (not by) Rikodou chakra that utilizes the Rikodou chakra for application just like the Rinnegan. In other words, this means RSM is an ability, not a state. And it also means not everyone who has Rikodou chakra and knows NE can use it.
It is the key, hogoromo is kaguya's son and she is the juubi pretty much so he inherited some of her power. This is why those who become jinchuriki of the juubi are said to have the same power as the sage of six paths. Rikudo chakra came from kaguya so it all fits.
I can ignore DB when the manga doesn't support it an example is temari blowing away the universe or naruto comprehending all of creation. Comprehending all of creation means having knowledge of all creation, this includes past, present and future which are part of creation. It is obvious naruto doesn't have that power. The DB in my view should only be used when it doesn't contradict the manga and only when the manga supports it.
The conceptual idea of this post is perfect. The only thing is that a Juubi Jin does not have the same power as Hagoromo right from the beginning. If their chakra fully matures, then yes, they'll have power equal to Hagoromo.
