Good list. I'd say those 4 moments and "He laughed" are OP's top 5 greatest moments.
Although, to be clear, I think these 5 moments are OP's anime greatest moments.
If we're talking about OP's manga 5 greatest moments, I'd replace the "Arlong Park Walk" (since it's an anime original scene) with the entirety of Nami asking Luffy for help and Luffy lending her the straw hat, before he says of course and we got the reveal that the other 3 SHs are there already.
Basically, the walk makes it for the anime, but the Straw Hat lending made it for the manga.
