Sanjis input has no bearing on the situation. It has no affect on nami and her thoughts on the situation and shes handled her business on her own.
Difference being if zoro didnt step in after the fight between ussop and luffy then luffy wouldnt have just about kept himself together and acted like a bitch and a shitty captain like he did on wci where he let sanji walk all over him and started begging the exact response that a crew could fall apart for even nami was telling him to leave.
