That's true, but when people use LaTeX they always do it properly with all the semantic information included, when people use Word they rarely do. WYSIWYG doesn't stop you doing things properly, but it does make it easier not to.
Hah, I wish that were true. Since the LaTeX stylesheet language is a terrible stack-based monstrosity that nobody wants to edit, real-world LaTeX use is riddled with manual formatting, especially nonsense like \vspace{}. In any case, WYSIWYG doesn't make it easier not to do things properly; *Word's* specific implementation of WYSIWYG makes it easier, by making lots of semantically-meaningless formatting commands easy to get to. Nobody is saying that a wikitext WYSIWYG editor ought to copy the interface of Word.
In any case, if we're taking LaTeX as an analog for wikitext, there are LaTeX WYSIWYG editors (like LyX), so the analogy isn't much of an argument against wikitext WYSIWYG editors.
