-Enma has everything to do with Hiyori, its was her sword before being passed down to Zoro and it reacted to Hiyori playing the Shamisen, Momo can't afford to move from where he is, also the Snake Slayer belongs to him, Also thoses are potential plot points Zoro can easily get involved in, Remember how Orochi is the one who killed Yasuie ? either Zoro needs to get revenge from Kaido or Orochi for that, so Pick your poison.
-So Hyogoro and Kawamatsu mentionning Ushimaru, then Mentionning Ryuma while talking about Zoro in the same Page is a made up plot point ? Yeah...
-You're partially correct, it was never suggested but it was implied, but yeah lets not get lore on black blades in the Arc of the samurai, and considering there's at most 6 arcs, which Elbaf shouldn't be that much of a threat for it to be an arc where Zoro gets a black blade. If he gets 3 Black Blades at the same time then that shits on everyone who can't make a black blade, Especially since making a black blade is an individual feat for each sword, its not a combined thing.
-I never said it wasn't, but while we know that, Zoro doesn't, as far as Zoro knows Sanji is still not down and he needs to stay up until after the Raid
