It subverts the hard work idea. While Goku had the privilege of being Saiyan, he was low class and the whole plot was about outdoing someone. Luffy continues to fail upwards. He gets pretty much every convenience and succeeds in spite of himself, like getting a grand fleet when he doesn't care or having precious lore at his disposal when he deliberately blows it off. His lineage and "fate" hands everything to him and it's the only real counter to the antagonists who are part of the same system.
