Stephen Paul tweeted that this is going to be the big one. He never says things like that so I am hyped.
As far as world building I always found One Piece to be extremely rich in its content and very consistent in how it evolves. Now granted I too am the type who thinks, aw Fuji could have thrown away some priceless stuff or what if an animal was hiding in some of that rubble? That kind of thing is best not to think about for me personally, lol. And then I do wonder what news papers have to say about characters and places as well. Do they go into detail over an admirals abilities or the strange geography on certain islands? I imagine they do occasionally and people choose to believe what they want. For example, Sanji read the encyclopedia on Devil Fruits when he was a kid, he didn't believe what he was reading and barely payed attention to the curse aspect of them. So while he had hope that the Clear Clear fruit was actually real he barely believed in them when he met Luffy and the aspect of drowning didn't even dawn on him when Luffy started to drown at Baratie.
As far as life on grand line being much more livable than what we might have thought in the beginning, It reminds me of friends who found out I grew up in South Central Los Angeles. The way they spoke, I lived through world war 1! From what they heard in the news they assumed I was dodging bullets, running away from gang members and getting beat by the police every day! Now each of these things happened to me, but they were super rare occurrences and life was 99% peaceful for me and my family.
To me the One Piece world is so alive. If you look at every flash back that happened in the North Blue with Cricket, Doflamingo, etc, you can even see the style of clothing is different from other regions of the world! I mean it's really subtle but it's there for anyone who looks deeper into it. So many things happen off panel or far in the back ground away from the main story but it still comtributes to the over all narrative and I love it.
I feel like One Piece can be as silly or realistic as it wants and for what ever reason I give it a pass. I think that this aspect of One Piece is one of its more endearing qualities. It can be super serious and logical or it can be completely off the wall and silly at the same time and it's completely ok. The thought of young Franky removing his organs and replacing them with some old ship parts is just so unbelievable but hey, he runs on cola so it's all good!
I just jumped in and I really don't know what the discussion is about. Sorry in advance.
