"the 2 of us have nearly killed each other many times". That doesn't actually have to be everytime Garp and Roger fought, Garp and roger were on the verge of death. It can easily be they were switching back and forth. Sometimes Roger nearly killed garp, and sometimes Garp nearly killed each other.
That still indicates Garp and Roger were on the same level since one was never always ahead of the other, they were always neck and neck, leading to them to almost kill each other, but both were unable to finish the job.
Him not being able to do it now = nobody being able to do it?? what?
When did I say this?
Luffy doesn't = everyone. Just like you made a scenario of where somebody can be 10x stronger than roger, and not be able to finish the grand line.. I'll make a scenario of someone who is skilled in everything, and is 10x stronger than roger, and can finish the grandline on his own, and still be called the Pirate King. But wait.. that type of a person won't exist in one piece... just like somebody who is not equal to Roger's strength won't be the Pirate King in one piece.
This makes absolutely no sense. Actually, the first half does, right up until the bolded. Someone who is skilled in everything needed to travel the entire world will never exist in One Piece. Therefore, there will never be a person in One Piece who can become Pirate King by relying on only himself. He must have a crew consisting of people who have something needed to complete the journey, and since no one person will have anything, he needs many people, a crew. No crew=no Pirate King, no matter how strong you are. Therefore, it's not a rank of power. A person who is extremely weak can become Pirate King if his crew is strong enough. Look at Buggy. Buggy is the joke of the One Piece world, but he is someone who can legitimately become Pirate King because there are strong people who are willing to follow him. Someone like Buggy, who severely lacks in power, can get enough people to join him and fight for him, and if they travel the world completely, he'd become Pirate King simply for being their leader.
Remove luffy's power from every arc, and keep his crew.. he'd be dead against buggy or even Morgan..and in fact he probably wouldn't even be the captain.
Why is it that luffy gets stronger every arc, yet you are claiming being Pirate King has nothing to do with strength? Why is it that luffy needs to keep getting stronger.. yet you are claiming pirate king has nothing to do with strength?
Why doesn't luffy just stay the a mid-tier, and become the pirate king??
Because to become the pirate king, you have to become the strongest on the Sea.
No. You do not. If Luffy was the strongest man in the world, what good would that do him when he can't feed himself? Or treat himself? Or navigate out of the Grand Line? Or keep his ship together? Make Luffy stronger than Kaido, and toss him back into the Grand Line. How is gonna find One Piece if he's completely on his own then?
The fact of the matter is, it doesn't matter how strong you are IF you don't have a crew. Strength is a factor, I admit, because you have to be able to beat your enemies and people who stand in your way. But none of that will happen if you're stuck in one sea, on one island, lost, starving, dying and with no usable ship. Take away Luffy's crew, and he'll never become Pirate King. Take away his power, and it's still possible for him to be Pirate King. The right crew is a much bigger factor in becoming Pirate King than the greatest strength.
These two panels sums it up, from Luffy himself.

Pirate King is a title, that is even above the World's strongest sowrdsman, according to mihawk. And its a title above the Yonko, who are indeed the strongest pirates on the seas right now.
Nope. Mihawk said becoming Pirate King is a task harder than the task of surpassing himself. And that's because of two major reasons:
1. Accomplishing the goal of surpassing Mihawk to become WSS is straightforward. You simply train your ass off and get stronger until you can fight Mihawk, and then you do it. Becoming PK is far less straightforward. You HAVE to travel the world, and you HAVE to find something. You have no idea what this thing is or what it looks like. No one knows what it is, and where it is is only a rumor on an island that is extremely difficult to get to.
2. There are more people gunning for PK than there are swordsmen gunning for WSS. By default, there are going to be less swordsmen in the OP world than there are pirates and fighters since the former is a subcategory of the latter. Plus the fact that no one actually has to stand in another's way to becoming WSS. Realistically, if someone is trying to becoming WSS and you want to as well, you don't have to stop them. If someone wants to become WSS, they don't have to prevent Zoro from doing so since they can just defeat Zoro afterwards and take the title from him if they're good enough to beat him in the first place. PK, on the other hand, do have people trying to stop you and getting in your way. Add this in with the World Government and Marines actively and constantly working to prevent anyone from becoming Pirate King, you have much more obstacles in becoming PK than WSS, which is why Mihawk said it was simply a more daunting task that surpassing him.
You still haven't explained how the current generation is superior to Roger's. All you have been doing is trying to counter my reasoning as to why they aren't stronger than Roger's. But you haven't provided any reasoning as to how Shanks' generation is stronger than Roger's. And how all of them are stronger than Roger/WB/Garp/Sengoku.
They're not superior to Roger's, they're on Roger's level. Weeble, someone whose strength is like Whitebeard's when he was young, isn't the World's Strongest Man, it's Kaido, indicating at least Kaido has reached the level of Roger's era. Unless you think Kaido low-mid diffs every other top tier of this generation, then yes, they've caught up.
