Very much appreciated, thanks.
While I understand your point about impact, I think that is somewhat subjective. By impact, you mean something being done in an appealing manner. Whether something is impactful is subjective, it depends on the reader's taste. The WG have no importance for impact. Their goal is not to glorify the achievements of Pirates or get people excited.
If Luffy hypothetically defeated Katakuri by poison, then what would it matter to the WG? Nothing, because it doesn't really change the conclusion.
If impact is so important. Then how do you suppose Cracker's defeated would be narrated to the WG? How Cracker was defeated wasn't exactly a fair fight. So what if the WG heard that Luffy ran away from Cracker for 11 hours despite the aid of Homies and Nami until he got irritated to the point that he got complacent which gave Luffy the window of opportunity necessary to land a finishing blow.
- What does it benefit the WG if the story is more impactful or not? It doesn't, it doesn't change the conclusion.
If the WG are not there to witness it, and they do not have the details, then how do they know it was brute strength that resulted in the conclusion? They do not. They'd need to be there to verify that. Most of the time, the WG are completely oblivious to the fine details beyond the facts.
As impact really has no basis, I don't see how impact has anything to do with why bounties are for the most part related to strength.
Bounties just don't get significantly higher after 300m, but I don't see what appearance has to do with strength. Appearance is just aesthetic. Someone looking cool doesn't make them strong, it just means they look cool.
The driving force behind a bounty isn't strength, it's the magnitude of the incident. There are many bounties that make 0 sense when it comes to strength because that isn't what bounties detail. What bounties detail is the accumulated magnitude of all crimes a character has committed.
If it's strength, then so many bounties are inherently flawed:
- Robin with a bounty of 80m at age 8 while Boa Hancock (A Haki user) at the age of 18 similarly has a bounty of 80m.
Quite a bit of what you say seems to derive from how you would prefer things from your perception. You more or less state bounties would look better if based on strength. While you're entitled to fill that way, the evidence does say otherwise regarding strength. How something looks and what something really is are different things.
