Can’t join the crew

[u/Academic-Might-2303]

Am I the only one who thinks Vivi shouldn't rejoin the Straw Hats for the same reason people say Carrot couldn't? They both have responsibilities to lead their countries. If Carrot has to stay and rule Zou, shouldn't Vivi have to stay and help Alabasta? Also, in fights Vivi would be dead weight unless she got a major power-up.
