No, I'm saying Oda obscured the details because One Piece is a story constructed by a person outside the narrative. The characters don't think an speak for themselves. The world emerges from Oda's imagination so you do have to consider what Oda is communicating to readers through dialogue and the manner he chooses to convey information.
The Straw Hats were given vague details about Lodestar secondhand from a character who has not been there. Nami says this information seemingly clashes with information from another character who knows even more about the world. Inuarushi confirms that Crocus knows more and wouldn't mislead them.
The fact is that Oda, the author of the story who puts the words in the mouths of the characters, chose to obscure the details about Lodestar Island. He's obviously not going to leave something so important unexplained. He isn't a lazy or incompetent author who would take such a narrative shortcut (oh that place is super important, but you got spoilers so don't worry about it).
The Straw Hats will visit Lodestar. If that were not the case, Inuarushi would have explained in full, exactly what the final island on the log path contains, why it's so hard to reach, and how Roger learned those details.
Oda has also filled in more information about said final island. He wouldn't continue adding details if it were so unimportant. The name Lodestar was revealed in Roger's conversation with Oden and Whitebeard in chapter 966.

@Ghidorah:
It's always possible that reaching Laugh Tale requires one to go through Lodestar. Frankly, I'm fairly sure Lodestar and Laugh Tale exist within relative proximity to each other, making it at the very least a natural stop on the path.
That's also assuming, of course, that nothing else happens that may jeopardize the Strawhats' intel, e.g. a Road poneglyph imprint getting smudged last minute, some villain absconding with one post-Wano, etc….But I'm leaning towards the former.
More than a simple pit stop, I feel Lodestar's the "platform" necessary to cross over.
I think there's a good chance Big Mom steals the Wano Poneglyph before the Straw Hats get to read t.
