Can the Thousand Sunny be destroyed though?
Isnt it Frankys dream for this ship to Sail around the World?
Not just Sail, Franky has always being about Battle Tech, He wants a Battleship, not just any Ship
And during his Flashback, We saw that He was testing how Advanced his Battleships are by challenging Sea Kings
We also know that each SH Dream is Portrayed as Near-Impossible due to an Obstacle that gets Introduced in their Path
Zoro's Dream ---> Mihawk is The Obstacle
Robin's Dream ---> World Government are The Obstacle
Brook's Dream ---> Red Line/Grand Line are The Obstacle
Entire Crew's Dream (Laugh Tale) ---> Yonko are The Obstacle
Sanji's Dream ---> It was Hinted in Thriller Bark that Marines are gonna be his Obstacle
Usopp's Dream ---> It's Hinted that Elbaf's God of War (Royalty) gonna be his Obstacle
... etc
In other words, Oda created Nine Impossible Challenges & found way to Connect them to each SH Dream
So by EOS, Mihawk needs to be Defeated, Red Line/Grand Line don't Exist anymore, WG Dethroned, Marines Fixed ... etc
So the same should Apply to other SHs Dreams, Oda will Introduce a Near-Impossible Obstacle for Franky, Nami, Chopper & Jinbe's Dreams.
And just like Oda made Zoro Lose against Mihawk, showed us Laboon hitting his Head against Red Line, Robin captured by CP-9 ... etc
Every SH must have a Reality Check about how Crazy it is to challenge The Obstacle standing between them & their Dreams
Hence why i believe, Nami will discover that Everything She drew so far isn't enough cuz World Geography is Wrong, a New Storm must happen that restores World to it's Original Form, and Nami must endure such Storm & prove herself Best Navigator
Regarding Franky, all of this means that Thousand Sunny should greatly suffer which would give Franky his Reality Check.
And i've already said it long ago that this Lurking Legend is Original Ruler of Sea Kings (Before First Poseidon was even a thing)
Meaning that in Final War, Sea Kings will go on a rampage everywhere (Adding that Storm i mentioned, that's why Tequila Wolf Bridge is being built for example, They are preparing for when a time comes that no Ship can sail!)
So imagine, World Geography changing, Storms everywhere & Sea Kings on a Rampage, No Ship can do anything, Everyone will take shelter in High Lands (That's why every major Island we've seen so far, have their Royalty living above Ground Level or shaped to protect from Floods & Storms), even Water 7 that doesn't have such advantage & should be First to get Destroyed, Iceberg confirmed that He is gonna turn Water 7 Mobile (Similar to Germa Kingdom, so that should save it)
This is the moment where Franky, Jinbe & Nami will prove their Skills as Best Battleship Maker, Best Helmsman & Best Navigator.
And as i mentioned above, before We get there, Franky, Jinbe & Nami must get their Reality Checks & thus Thousand Sunny should suffer soon against this Lurking Legend Powers
