Well yeah, I've compared Oda to Sanji before and joked he's Oda's self insert too. It would make a lot of sense given how openly/proudly perverted Oda is. It's funny how Sanji rescued Nami from a forced wedding and then he was forced into one too, with Nami being relevant in that arc trying to save him too. But he ended up carriyng Nami again funnily enough too! And then there's Lola connecting both of those arcs directly...WTF ODA!? Way too big brain!
Luffy would have someone else save him. Sanji's a weak character. Most people don't watch one piece for Sanji. Only way he is relevant because he is compared to Zoro and fetishized by fujoshis/gay fandom.
