Did Obito forget or it's just not possible?

[Nidds]

Obito has said Kakashi's power is temporary, did he forget that he had Hashirama's DNA/Chakra infused within him. So off a technicality it may have been possible for Kakashi to keep MS without going blind? Or is this not possible?

 

[obito uchiha the wraith]

its possible I think kakashi has double kamui permanently and maybe a chakra boost.

 

[Young Thug]

since when did DNA transfer into chakra?

 

[Itachi 4 life]

I think he will go blind anyway.

Chakra doesn't last forever, even with Senju DNA
