I mean, everyone retroactively suspended their disbelief or otherwise "Band-Aids heal everything" and "no one dies outside of flashbacks" wouldn't have become facts of the series in the fanbase. It's just that people rationalize it as an aspect of Oda's writing style instead of an in universe explaination. Which is the contrast Tolkien tries to make between suspension of disbelief and being a part of the world you built.almost
Something people didn't suspend their disbelief over would be stuff like Kuina dying from falling down stairs or the idea of tiered devil fruits, both of which a core segment of fans don't believe. Meanwhile everyone accepts that Pell survived because of lol Band-Aids.
Pell was the start of the "Nobody Dies in One Piece" shtick. Outside of that, I didn't have a big qualm with it. In fact, I liked it because OP is a good example of how to keep stakes high and have actual consequences without killing people.
As for Kuina, I don't believe it's a fair comparison since that was early One Piece and Oda was still fine-tuning his own method of a sad flashback.
Kuina dying in such a mundane way was likely intentional. The talented young swordswoman who wants to be the strongest in the world...dies from falling down the stairs.
