Yeah but ET is also a jutsu, so there are ways to have the same pair of eyes twice in 1 world.. I don't understand the rest what u said .

Itachi's eyes are the same as edo Madara's Rinnegan. Fake. They was revived at the time before they died so they still had the powers they had before they died. Like when Madara was revived his fake Rinnegan went away because Obito had his real eyes same would happen to Itachi.
