These are all your assumptions. I’m talking about facts here; and besides Shanks says it in the page you posted “It’s a wine from my hometown!”
Oda may have retconned Luffys fruit; but that isn’t the same as completely changing the canon. All Oda did was give the name of the fruit that’s been hidden.
But again you’re here saying “It doesn’t matter what is canon.” And if that’s what you think what’s the point in discussing the story at all? Cause what we are told outright:
1. Shanks’ home is God Valley
2. God Valley went missing from the West Blue 38 years ago
3. Shanks brought Whitebeard wine from God Valley 2 years ago
4. Islands have been known to be moved in One Piece as another island from the West Blue was found in Paradise and is currently in the New World right now
But again, you think we should ignore the canon?
I used to believe this, but, Lulusia changed my mind.
If you look at Lulusia's hole, it's just... a giant dark void. IE, gravity is FORCING EVERYTHING, straight down.
So, I think God Valley was Imu's last Mother Flame charge for Uranus, until York sent Imu some fresh new Mother Flame.
So, God Valley... sunk. Just like Lulusia. Hence the name, valley.
If that's the case, I think Shanks' hometown is probably some random West Blue village Roger stashed Shanks at until he was old enough/the WG found Shanks and tried to take him back.
Sengoku was pretty adamant about God Valley's fate. At first, I really wanted God Valley to be Shanks' territory, but, at this point I'm convinced the island sunk.
Shanks was introduced drinking sake from some random bar in the East Blue. Shanks isn't like the CDs, he just enjoy food/drink, it doesn't need to be the pricey stuff. Shanks bringing Whitebeard some random ass sake from his hometown is also just hilarious to me.
