I think you are right in that these characters have earned these things. You cannot forge the strongest black blade just like that, great swords require great swordsmen to actually use them like Enma being wielded by only two guys while it has been in the country of Samurai for so long. Similarly only the strongest can use their devil fruits which seem to be the best. Mr 4 had an OP devil fruit, Robin has one, even that weight changing guy from Doffys had a potentially great fruit.
The reason for these top tiers having the strongest devil fruits and swords is because they themselves are the greatest. And when you spend your life ready for battle you somehow find the best tools that will give you the best ability that complements your style and power.
I know people have been shitting on Mihawk because the strongest blade thing and WB and Kaido having weapons strong enough to channel their great strength and not break is somehow messing up with their power scaling.
Or how Luffy is getting disrespected like having an OP devil fruit and getting carried by it. But in both cases the characters have earned these things. Mihawk forged the strongest blade and Luffy only awakened the Nika fruit because his mind and body had finally reached the level that would allow it to be awakened. Call it whatever you want but it has been clear that Luffy worked and trained hard to earn that awakening. In 800 years nobody had awakened the fruit meaning nobody had reached the required mind and body level to awaken it.
