Okay let me say this....
Prophecy/Reincarnation thing is not new to shonen manga.....but OP has given completely different treatment to this thing....lets see
In case of Naruto, fourth hokage sealed nine tails in Naruto because of the prophecy and destiny while Dragon didn't give a shit about Luffy......
It is Luffy and Ace wanted to become pirate while Garp wanted them to become Marines.....
Luffy ate "gomu gomu no mi" accidentally...and became rubber.....
He gives the vibes of Roger according to many people even though Ace being the son of Roger......
WB preparing Ace to become next PK but he died in between because of BB......
Luffy decided to take Zoro as a comrade because he saved that little girl not because of some fate....
Most of the time fate offered him choices....
examples
1) like save Nami from Arlong or look for another Navigator
2) EL is said to be impenetrable fortress.....it is difficult to invade.....people who opposed WG are "fated" to die...Luffy and co went against fate and they were rewarded....
3) Same with ID/WCI.....
Remember Wano started because Luffy intercepted the phone call before PH....
At Saboady Luffy succumbed to fate and he experienced heavy loss....at MF, he couldn't go against the fate and save Ace....
So while it can be said that the fate guided Luffy to where he is , it is he who made "choices" and got rewarded/paid price.....
I will add more if I can think of more content....
