He can snatch physical objects and physical abilities, not spirit and willpower
Oh true he can't steal magic power, well, in either case he can beat Kaido without any type of snatch, snatch is just an extra to do it faster
Now THAT is true
As a One Piece fan (having read all the current chapters) and a Seven Deadly Sins fan (having finished the series) In my opinion I'd say Kaido would be able to deal damage to Post Purgatory Ban but not outright kill him or even win for that matter. I saw a comment saying Ban spent 30 years fighting the Demon King which isn't true by a long shot: Purgatory works differently when it comes to time (1 minute is 1 year) and Ban spent 720 Years in Purgatory acclimating to weather that would kill almost any low tier Warlord of the Sea (acid rain, subzero temperature, storms and the like) which he spent 60 years fighting the Demon King with Meliodas and Wild until he managed to temporarily neg the Demon King's unique power The Ruler and when he returned to the human word he was almost equal in terms of strength to an even stronger Demon King who possessed Meliodas body (this DK being able to casually one shot Zeldris (although Zeldris was weakened)). The existence of TWO Demon Kings existing at the same time was enough to cause worldwide catastrophes (just because there was the DK and Meliodas). Post Purgatory Ban scales around roughly 400k to 500k in base since:
The Sinner (OG Demon) with a power level of 360,000 was considered to be half of the Demon King's power before it was split yet was casually nuked by Sunshine Mael (who's Sunshine power was actually slowly growing weaker since he was using it AFTER high noon) who refused to fight the Demon King (although I'm not too sure why he didn't help it could have been because he feared dying and not being able to resurrect/lead the Goddess clan since he's the last Archangel). So Post Purgatory Ban should scale higher than the original Sinner but not equal to the Prime Demon King. Considering the Demon King (Meliodas) was taking damage from him and was enough of a threat to one shot a weakened Zeldris and make Mael tag out we can say that he wasn't at full power (having just awakened).

No, he can't damage him, Ban is too powerful for the one piece world, he would solo it without any serious injury
He gettin blitzed
Well, if ban could even steal meliodas's power, then he definitely can do it on kaido which i think weaker than meliodas
BLITZES
Dawg he’s immortal 😭😭
Post purgatory ban isn't
This post isn't either so just leave it dead
