I think he meant that in more general terms: Kakashi's power is borrowed from the Uchiha, not Obito specifically. I get the impression that Tobi somehow considers himself to be the embodiment of all Uchiha, and as such, he is entitled to all the sharingan and rinnegan in the world.
Tobi has Obito's eye, but he's not Obito. In Tobi's mind, it's not borrowed power because he's an Uchiha using the Uchiha's power.
Exactly :ice:
I think another thing that was confirmed this chapter was the fact that Tobi CAN'T use Rinnegan techs for whatever reason. This is probably why Madara entrusted him to give the eyes to Nagato, because Nagato could use them.
Regardless, it also says that Tobi is blatantly going against Madara's wishes by inserting the one Rinnegan as his left eye. He can't use it, and Madara was probably aware of that, so as you said, Tobi probably thinks of himself as an embodiment of the Uchiha and also,
greater than Madara.
IMO the only one Madara would trust to transport the eyes and the only one who would consider himself better than Madara is his own brother. The only way Izuna would turn out this way (evil) is if Madara forcefully took his eyes or donated them but was promised that Madara would fulfill his wishes and bring the Uchiha clan to superiority (which he failed to do).
Izuna (in this scenario) would probably feel like Madara failed him and take up the mantle of the Uchiha clan's leader/savior for himself. Madara entrusted him with a plan, and in the end he decided that he'd become the Juubi's host himself (look at how much he's accomplished already!) and disobey Madara's orders ONLY after Madara had died.
This would explain why he was so scared upon seeing Madara revived as an Edo Tensei. He knows his brother could whoop his @$$ and only acted during the time when he was absent.
Remember how when Madara was initially revived via Edo Tensei, he spoke about expecting Nagato to revive him. Tobi (upon Pain/Nagato's death at Konoha) claims Nagato's Rinne Tensei was meant to be for HIM (not Madara) and we also know Tobi wants...

A complete body. Probably meaning that he wants the ability to use his MS again, the Rinnegan, and be considered a So6P in a sense similar to Madara (which he probably had a shot at before his eyes were taken). This leads me to believe that Izuna is in a predicament where he CAN'T use his power fully (possibly something to do with his body) and he resents it as much as he resents the Uchiha and his brother for stripping him of his entirety. From the guidebook here, it says loosing one's eyes as an Uchiha (whether they are given or taken) is the same as
complete self-destruction.

Sorry for going off on a tangent xd but I'm 100% convinced Tobi is Izuna from what we've seen so far, and I'm standing by it even if I can't explain it 100%. To me, as long as this page exists, Tobi is Izuna.
