@Don:
I dont know why so many try to argue why Zoro as a swordsman shouldn
t\doesn`t have to use Haki…
I can't speak for everyone else who feels that way, DonQ, but the main reason why I resisted the idea of a hakified Zoro was because at the time, haki was presented as this rare, all-powerful "Force"-like quality that seemed akin to DF (this was in SA, pre-timeskip, when Rayleigh was using it to solve just about every problem that he and the SH ran into in the auction house). So of course I resisted it for the same reasons that I fought DF and seastone swords: haki seemed too powerful and too much like a "cheat".
But … as soon as we saw it in different contexts: saw that it wasn't invincible and all-powerful, saw that even minor characters like Margaritte could have it on a small scale, and eventually found out from Rayleigh that it's something everybody has ... that's when my views started to turn. In fact, my views were so changed at that point, that by the time Zoro appeared in SA again without an eye, I treated CoO as if it was a done deal for him:

Quite a change from two years earlier!
If I'm still hesitant, it's for the reasons boiga and I have already discussed, but the evidence Urouge has given us is enough to ease most of those hesitations, so I'm ok with it now.
Mugiwara_no_Ice summed it up well. If everyone has a bit of haki and the potential for strengthening it, then that makes a gifted haki-user no different than, say, someone who is gifted in math, or spelling, or running a four-minute-mile, or whatever…
@Urouge:
Yes, I do. It's a DF attack, so it should be blockable, but I could be wrong. I do not think, however, that using haki on the ghosts will hurt Perona, but Robin's ability hints that could be possible too.
Robin's ability is a solid, human-like appendage though, not a misty, transparent thing that can move through walls. Robin can make an arm appear on a wall, but I don't think we've ever seen her make an arm pass through a wall – we've seen Perona do that several times. Robin's punch "though" Vivi was just an optical illusion. So I don't know if we can compare their DFs since one is solid and the other is ...well, what are Perona's ghosts made of exactly?... light? mist? fog? old bed-sheets?
(To be honest, I hope you're right about the ghosts being stoppable and not harmful to Perona, because then that makes the negative hollows a convenient prop for haki training -- and, an endless source of amusement for Mihawk whenever his apprentice fails to destroy them).
:ninja:
@Louis:
The way she has them blow themselves up is a good indication of that.
Interesting point! I think that does prove that their DFs are not similar, because if Robin held a small explosive – say, a firecracker -- in her hand, the explosion would injure her. But this doesn't prove that Perona's ghosts can't be negated by haki, just that it probably won't hurt her.
@HopelessFollower:
So when you end up with a fight where two fighters both have haki it's not the strength of the haki that determines the fight, but the skills and willpower of the fighter, which wouldn't change the series in any significant thematic way.
Well said.
Ok, I think I'm more or less convinced now that even if the entire crew got some form of haki or another, it wouldn't turn things for the worse.
