You know the vivre card never said that lmao
Man don't quote me with this drunk stream of consciousness rambling please.
There was a six year gap between when he lost his arm and when he became a Yonko so there is a possibility that he got stronger.
As for motivation, haki is tied to ambition and guess who's haki was described as amazing? Not Mihawk or a YC1 level admiral but Shanks.
Only in your world does Mihawk mid diff Shanks. Currently he is waiting for a swordmaster stronger than Shanks. Meaning no one else is on the radar. We know admirals are on the same general level. Fujitora is a swordsman. So if Shanks gets mid diffed then every admiral gets low diffed by Mihawk.
Mihawk couldn't even get close enough to talk to WB and he beats him with a pocket knife? Your hero is someone who got replaced by a fucking toy?

Got legit retrenched
Mihawk PK+ level character is currently being threatened by fodder marine #343 to come out of his hidey hole and go to prison. Compare that to Shanks who gets treated as an equal by the people who give Kong orders who gives Akainu orders.
