i don't think its impossible for sanji to get it to me sanji getting it makes narrative sense his father did everything in his power to make his kids emotionless yet sanji is the one that still retained everything i personally see it as the biggest f u to judge if the son he considered a failure not only surpasses his brothers and him but is a conqueror as well and for me rayleighs words ring true for sanji as well most people that have made a name for themselves have it and as much as many fans take sanjis words in thriller bark as a joke he did say he would be a huge threat to the world government this to me is making a name for himself plus he is a germa prince and potential future ruler if oda goes that route now as far as how oda will make it happen i'm not to sure but if its one thing i can give sanji is his will to not hit a woman its concrete and has not faltered he has very strong belief in this all throughout the story and even if his ambitions are not as great as luffy/zoro its still his own ambition and could lead to it happening heck look at katakuri who ambition was to protect his fam or yamato who just wants to break the chains and be free these arent super stong ambitions yet they have coc so for me i'm not counting out sanji yet but either way if he does or does not get it i won't riot lol these are just my opinions
