This series needs some stakes. If Oda can't kill characters at least let Kiku's arm be off.
Just accept that Oda refuses to acknowledge that One Piece is older than its target audience.
It has almost as stakes as Dragonball always had, despite the fact that DB always had a "revive everyone" free deus ex machina at the end of every arc.
Dead people aren't actually "dead". they can train while dead and come back stronger. BIG STAKES.
It's a happy story of "good x bad" no matter how he tries to "cover it up".
The less we try to paint One Piece as some edgy shounen like JJK or Bleach, the better. Different approaches.
