I just don't think the history of the planet would be enough to give credit to Vegapunks claim.
Do you remember why Vegapunk died? because what he was researching could only be learnt from knowledge only available during the Void Century. Vegapunk's genius was 500 years ahead of the current generation... and even then he admits the Ancient Kingdom were still far more advanced than anything he could produce.
I really don't think you understand how important the history is.
I also don't understand how you, or anyone... can see the Gorosei actually make an appearance simply to make sure Vegapunk doesn't say anything related to the Void Century. And then question how much of a threat the Void History is.
The Gorosei rarely come down to do anything... yet all 5 of them came down... to stop a broadcast speaking about history... but we're really going to claim this history can't be that important, lol.
I agree, knowledge is power. But I don't see how having full knowledge of the past would apply power to whoever finds the One Piece. Like, practically, how do you see that fitting into the story?
Easily, the story literally explains it.
For one, the world thinks the world is ruled democratically.
There are approximately 200 countries allied with the WG... paying tributes, taxes and whatnot.
They attend Reverie, they listen to the Gorosei and take their counsel.
Like Joker said if you recall... just knowledge of Imu's existence would shake the world. Remember how the WG tried to kill him because of this knowledge? The WG have ruled the world for 800 years now.
What do you think would happen simply from the world learning... the WG have lied to them? All 200 countries will end their affiliation with the WG. All of their influence will end then and there.
Again, if you have any recollection of Egghead, it's like most of it has been forgotten - not sure people even know the point of Egghead arc. What did Vegapunk do that the WG was trying to stop? They were trying to make sure Vegapunk's broadcast wasn't heard..
But why are they concerned about a broadcast? Vegapunk said the world government was trying to literally sink the world. They sunk a tonne of countries during the Void Century, but Vegapunk can't prove it unless he has access to the One Piece - the 9 Poneglyphs at Laughtale that narrates what exactly happened during the Void Century.
If the world finds out the WG whom they follow is actually trying to kill them... the WG would lose all credibility.
If Buggy claims it, knows the history, how does that make him able to decide the fate of the world?
Of course. Access to knowledge that would end any trust in the WG.... people would be looking to new leadership. Furthemore, access to Ancient Weapons. This is knowledge only gained from reading Poneglyphs. Only reason the SHs knew Pluton was in Wano was.... Poneglyphs.
It's ironic how people don't seem to understand this story is literally about the WG stopping people from reading Poneglyphs when it comes down to it, lol.
The Void Century's information like VP himself says... also has the answers to the energy he's trying to create - wars are mostly about energy like Jimbei said, it would pretty much end a lot of wars. Access to technological advancements. Ancient Weapons. Influence. It literally makes you the most powerful person in the series.
Also to note that when Rayleigh speaks of finding the truth of the world, and Usopp tries to ask about the One Piece, he speaks in a way that implies those are separate of each other
OF COURSE they think it's separate things, they don't know what it is, lol.
Person A) David, What's in this box?
Person B) David, Where can I find a book that gives the recipe to making cake?
To both people, they're asking different questions. They don't know the recipe is in the box meaning they're inherently asking the same thing. This is literally what Robin and Usopp did.
Again, question no one can answer:
What else is at Laughtale besides Poneglyphs?
