Isn't it "funny" that Imu destroys Lulusia in the same chapter where Luffy happily talks with his crew about what is at the end of his dream?
Like, you see this.....
...and after a few pages you have this
I think, if this is no coincidence (which likely isn't, Oda wouldn't randomly put all of these specific scenes in the same chapter), it could be taken as another proof that at the end of Luffy's dream of becoming the pirate king there is something bigger than that, something like maybe uniting the whole world under his crew, the whole world being one "crew" of friends (literally a one piece of friendship lol) and of course Imu stands in the way of it, because they want to keep the world divided into four seas, various nations with social and racial differences fueling hate against each other (instead of directing it towards the ACTUAL enemy).
Imu's style is surely divide et impera, while Luffy wants everyone to be free and happy. I also think ultimately the concept of "one piece" will be applied to the whole world, the Red Line will cease to exist and so all the separations and divisions it symbolises, not just physically as one huge mountain in a world of sea but also as the house of Celestial Dragons and World Government
Absolutely crazy that One Piece has gotten to a point where a seemingly straightforward phrase like:
“One Piece is the story of Monkey D. Luffy, an ordinary boy who gained special powers after eating the Gum-Gum fruit. His biggest dream is to set sail and become the King of the Pirates”
