Just look at how the fights panned out. Where in any of those fights would haki have changed anything?
Just because you have Haki and use it, it doesn't mean you are guaranteed victory. Luffy proved this against the BoA sisters.

-Franky wouldn't have been able to pierce Sasaki' stomach and that may have been his last laser he could do. Then we would have Franky vs Sasaki in CQC, Franky without Shogun against an Ancient Zoan...
-Robin wouldn't have been able to "clutch" Black Maria's body (since it's not the same to bend an human body and a bronze statue) and Robin can't fight anymore like we saw in the last chapter so easy win for BM.
