It’s also not nice to write longer text in monospace. Or to have long URLs interrupt the text just because you want a hyperlink on some word. Or having to lay out tables by hand like ASCII art. Seeing *this* isn’t the same as seeing this. And you need custom editor software anyway to have affordances like TOC navigation.
> long URLs interrupt the text just because you want a hyperlink
This annoyed me until I realized pandoc supports separating [the link text] from the link location.
[the link text]: </url/to/resource>
"`title` parameter of the <a> tag, if converted to HTML"
Tables by hand, I hate. But I don't quite agree with the first sentiment. For longform prose, it isn't that unusual for people to work with all editing marks visible. Writing novels, I absolutely write using monospace, because it allows you to more concisely control large amounts of formatting easily.
