So JoyBoy allowed the AK to be destroyed because it was being overrun by idiots?
Better to rebuild everything than to let them get their hands on the AWs?
I think Joy Boy was Hiriluk, not Dalton, because Ishi-20 remind me of 20 Founders, and Snowy Tale is direct reference to Laugh Tale,
Also, this means that Ancient Kingdom was covered in Laughter instead of Snow, and just like Hiriluk's Dream was to turn Snow into Sakura to oppose Death, this means Joy Boy's Dream was turn Laughter into something miraculous, which indeed fits the entire theme of Story & Luffy, not to mention that being First Pirate means He invented Jolly Roger and according to Hiriluk's Explanation, the skull represents impossibilities, and if we go to it's most basic definition, it simply represents Death, so Joy Boy wanted to turn Laughter into something that opposes Death itself (Chopper, Brook, Zoro seeing Death, how Luffy awakened, Sanji's Last Chapter, Robin's I want to live ... etc it's clear what kind of Crew are SHs).
Now for Dalton, I personally hope He is Davy D. Jones, that's why Imu was asked if He was afraid of Joy Boy or Davy?
Are you afraid of the Man who could heal the World? or the Man who planned it's Destruction? (Also, this Drum Island Flashback, suggests that it wasn't WG who planned sinking of the World, it was this Rebel Character)
Also, just like Dalton ended up the one who sit on Throne at the end, that means the one who should sit on Empty Throne is whoever Inherited Davy's True Will, and currently it's whoever Inherited Xebec's Will, and that's Loki, not Blackbeard,
I mean if Hajrudin is gonna end up ruling all Giants & uniting them, then Loki is destined for even greater Position, He is meant to rule World Government, He is basically Momonosuke of entire World.
The real question is, who is our Wapol? (Someone that all 20 CDs Fear), our Chopper? (Someone who is Embodiment of Joy Boy's Dream),
Our Kureha? (The Actual Best that Ancient Kingdom had to Offer in whatever They were Best at, which is probably Science),
