@Flipper:
Well.. You're talking about someone who supplies pretty much anything. Im sure with his empire he can at least attain seastone to create something that is "his life".
I understand where you're coming from but i mean come on, the biggest Broker of the new world?
What bothers me a little isn't necessarily that the most influential broker has A TON of Seastone, it's that we rarely see it used as a weapon. Just remove one pole from the colosseum and you could enhance dozens, if not hundreds of weapons with a power that can potentially defeat the strongest characters in the OP universe. Imagine someone like Vergo with Seastone brass knuckles, or Sanji using a tiny piece in his shoes (like Viper). It would be a massive advantage, but for some reason no one except for Smoker and Viper makes use of it. At best we see someone throw cuffs around if the plot demands it, like Usopp or Onigumo.
And yes, early on we could swallow it because apparently it's a super duper rare material, but now we know that the Marines coat their warships with it (!), the prison cells in Impel Down are all made of Seastone, and Doflamingo has no issues obtaining enough to build a huge factory.
And now that Devil Fruits are such a huge focus of the series (with Smiles, man-made Devil Fruits, whole nations trying to get ahold of powerful fruits and of course Blackbeard having his own agenda), I would love if Oda would address that there is a really convenient way to stand up against all those overpowered abilities, outside of haki. The guards at Impel Down are a good example of what I'm talking about. Sure, there was no way that they would catch Luffy and Crocodile with their Seastone nets, but they were the most dangerous type of fodder introduced so far due to the slight chance that they could actually succeed at stopping the protagonist. Likewise, if Doflamingo has no issues getting his hands on such a large amount of Seastone I would have really welcomed a squad equipped with seastone equipment, maybe under Pica's special ops unit.
But whatever!
