I think Loki is one those guys that thinks World=Home Nation(Elbaf).
I was more thinking about the line from a meta perspective. It's odd to me to introduce another 'End-of-the-World' as a potential plot point, when just around ten chapters ago the story pretty plainly introduced the ACTUAL main 'End-of-the-World' plot point. That was, at least in my mind, supposed to drive the story to get to its finale, but now it seems like the story has already forgotten about it.
As much as we can meme as readers about how pointless a lot of Vegapunk's speech was for us, in-universe it is the biggest deal ever. The stakes can't get much higher, but what kind of dialogue have we had from the Straw Hats about it? Pretty much nothing. That just creates a strange tone for me, as much as I may enjoy some of the panels this chapter.
