She literally can’t go back. She’s on the run from the WG now, and going back to Alabasta would risk puttings the citizens in danger. We all know what happened to Lulusia.
Imu can nuke a country in a matter of seconds, so if Luffy isn’t there then they’re screwed.
This. Vivi is smart. Once she realizes her father was murdered by the strongest forces in the WG, there's no way she's return home just to have CP0 or some other force kidnap/kill her.
Who in this thread wants to tell me Alabasta's pathetic military is actually going to protect Vivi from Imu and the WG? Huh? WHO WANTS TO TELL ME ALABASTA'S MILITARY IS STRONGER THAN THE STRAW HATS?????!??!?!??!??! HUH????????????? Luffy can solo the entire fucking kingdom, oi.
Alabasta cannot defend Vivi, and she would be bringing danger to her kingdom by returning there. Now that she knows she's a wanted woman, the place to go is obvious; piracy.
Vivi is the first domino to allow others to join, a queen who excels at connecting other kingdoms. We already saw this at Reverie, with her meeting with Rebecca and Shirahoshi.
Vivi's purpose as a Straw Hat is to unite the kingdoms the Straw Hats are connected with as a sovereign, as her status and stature is perfect to lead a revolution like this.
Imagine you're a rando in the One Piece world, and you hear that after her father was murder by the World Government, Vivi joined the Straw Hats, a Yonkou Crew, to revolt against the World Government. That's a way bigger deal than Dragon or Sabo making a declaration. This is the Queen of a founding nation stating the entire World Government is corrupt and declaring open hostilities against them.
This will lead to a new alliance, where Dressrosa, Sai's country, and others form a super-alliance of nations to stand against the World Government.
Since Vivi is so connected to revolution, she'll either rejoin the Straw Hats now, or meet up with the Revolutionaries now (teased with Cobra and Sabo) to discuss things.
Either way, Vivi's connection to revolution, the D, and the Ancient History will lead her to be the link that finally brings Luffy and Dragon together.
The Princess who stopped Alabasta's revolution, will join the Straw Hats to cause multiple nations to revolt against the World Government, which, to me, is really good writing.
Pre-time-skip Vivi: stops a good kingdom from being destroyed through revolution and becoming an evil kingdom.
Post-time-skip Vivi: stops an evil kingdom from destroying good kingdoms through revolution.

I am now formally withdrawing my support for Vivi as a nakama, there is no way in hell you're gunna have 2 Ds in the SH, this reeks of Law, this reeks of Yamato, this reeks of ultimate princess in distress arc format, the starter of the D thing is literally Vivi's ancestor.
I'm gunna hold out till 1088 for a certain someone and if that doesn't pay off, i'm officially retiring and deleting my account and tapping out of this ordeal.
The D is a shared, not given, name.
That was the entire point of the Sabo/Ace/Luffy flashback; it was Oda using a cute scene to show that the name D is shared with friends.
Ace literally gave Sabo the D (oh... wait... ah, fuck it, I'm letting it stand) when he called him "Sa D. Bo".
The World Government is obsessed with bloodlines and racial purity, obsessed with family lines and prestige. The D Clan was the opposite, and freely gave the inital D, meaning Dawn, to whoever amongst them wanted it.
All the Straw Hats will be D's by the end of the series, since they're all enemies of the WG, as they're Joy Boy's Nakama.
Roronoa D. Zoro
Nami D. Imu (you heard me)
Go D. Usopp (Nice Merry Go reference if Oda goes this route)
Sanji D. Vinsmoke
Tony Tony D. Chopper (I love this one)
Nefertari D. Vivi
Nico D. Robin
Cutty D. Flam or _______ D. Franky (Cola?)
_______ D. Brook (Bones?)
_______ D. Jinbei (Nile?)
_______ D. Carrot (Barrel?)
_______ D. Yamato (Oden??????)
Kurozumi D. Tama
Momonosuke D. Kozuki
The possibilites are endless
Speed = Spee D. Horse
Gaimon = Chest D. Gaimon
Foxy = Fox D.
Dread it, run from it. The D. is coming. DEEHAW!!! IVANKOV IS HERE TO GIVE EVERYONE D'S!!!
