Being old isn't a disqualifier, especially for Tsunade. Despite aging horribly she was still capable of fighting for hours against the villain sue that is Madara Uchiha.

And regarding Kakashi's qualifications, everything you've stated only proves he's excellent in a military position but the Hokage is much more than that.

We don't know the extent of Tsunade's history but she is regarded as Princess Tsunade, a shinobi who's likely seen more War than most of Kakashi's Era.

Add to the fact she's already been Hokage for 4 years under stressful times. There is no reason she would have retired. It was done because Kishimoto wanted Kakashi to be The Hokage.

I apologize if I sound hostile but this is a pet peeve I have with the ending.
