Sure, I can do emacs with softwrapping to write my next legal contract. I can also do text editing in Word for my next LaTex document. But I wouldn't want to.
This is not an obscure distinction to make.
Sidebar: Actually I much prefer a recent Word to WordPerfect 5.1. But the question was command line tools, and WordPerfect 5.1 is a good example of a terminal based document creation tool focused on creating, well, documents. It should be easily possible to make a modern equivalent - a terminal based editor focused narrowly on the creation of the same sorts of documents Word is good at. But I don't know of one, and a tricked out emacs doesn't really get there.
