I think authors premise is its Luffys retardation that put them in the situation they are in.
Had Luffy not provoked Meme, Meme won't have been in Wano, Zoro and Luffy woulda defeated Kaido by now, then go to WCI, defeat Meme as well and get Sanji back.

Thing is Zoro isn't a coward anyway so he went up there knowing perfectly what could happen. So I don't understand the complain. Nobody's complaining about Usopp having his skull cracked for example.
Besides, Zoro's words about Big Mom was said before he knew the whole plot, after knowing more, he was fine with it and didn't complain either when he heard Big Mom was in Wano.
Imo, the author is targeting Luffy for no reason, just pointed it out.
