Why would you derive that from my argument? Poseidon is a weapon, it's meant to kill people. I think it's a major threat, only you don't because you don't consider a crybaby mermaid capable of harm if pushed. It's you who doesn't understand the calamities controlling the sea with huge Sea Kings the size of Fishman Island could bring.Well, I said its ARGUABLE ; not that it isn't possible.
And judging from your entire argument, I think you want the entire world to be saved against Poseiden. What I am arguing is that it isn't a major threat. Calamities do occur and even if an island or two is destroyed, it wont affect the world in a major way since the attacks of Poseiden can be controlled.
1. Bubble coated ships work the same as submarines ... but what can they do? Float helplessly against the Sea Kings? You saw Caribou's crew against the Kraken, what more against a huge creature? Even the SH shook in their pants when barracudas and piranhas they're capable of taking out in one-shot attacked them.About submarines - I think bubble coated ships will work the same way as submarines.
About seastone - Marines use it on ships and weapons. We really dont know about the quantity yet.
About camera - Vegapunk can easily do something about it. And what more, he could easily make Pacifistas fight in water which solves the patrolling issue.
2. We don't know the quantity? Listen here. If it wasn't scarce then we'd be seeing Seastone bullets. Why are they instead made into bullets or nets? Because these things are retrievable, easily recovered. Bullets aren't, so we can imply scarcity.
3. Because Pacifista can take down Sea Kings and survive 10,000 meters underwater. Alright.
Your logical argument involves every island in the Grand Line and the Blues having Vice Admiral to Admiral-level fighters and Amazon-level citizens. It also involves the Marines spreading themselves thin over the seas which is a very bad argument. You assume many impractical solutions that wouldn't even work because if they did we might have seen it already. I'm not judging you, I'm pointing out flaws in your argument.This is the judging part. So nice of you to do it again.
I just believe in making a logical argument and listening to one. Everything else is shit to me.
