I think we've all head this theory before and if I'm being honest, I think its kinda dumb.
That theory that in the end of one piece, the red line will be destroyed and that this will somehow create all blue. Simply put, this theory makes no sense.
First of all, if the All Blue needs to be created, then it means that the All Blue doesn't exist. And if the All Blue doesn't exist, then it ruins Sanji's dream. His dream is to find the All Blue, not to create it.
All Blue is a legendary place. Its existence parallels the Sky Island and Laugh Tale. If the All Blue needs to be created, then it means Sanji was a dumbass for believing it and that these cooks were right. Don't think that's really the theme Oda's trying to push.
Furthermore, the issue of the All Blue has nothing to do with the connection of the ocean. The ocean is connected, via Fishman Island and reverse mountain. However the issue with the All Blue is that fish adapt to different environments and hence it would be near impossible for there to be a sea with all types of fish. Think about this in realistic terms. IRL, there is no red line, but there is no All Blue. Why? Because Fish stay in the parts of the ocean that they evolved in, that they are adapted to live in. A fish from the coral reefs would have a hard time living in the arctic and vice versa. That's why the All Blue is an impossible dream. It has nothing to do with the red line.
For an "All Blue" to exist, it would likely need to be artificially created.
As they said, the All Blue is the dream of seafaring cooks. It is a dream made into reality, much like DFs.
Ultimately, what this means is that the All Blue needs to be something that was created by the Ancient KIngdom, likely by some cook. This sea could be the sea surrounding Laugh Tale, or maybe it could even be some sort of secret underground ocean. Who knows.
But the All Blue definitely exists and isn't something that needs to be created.
