You can't drag a cursor down vertically and know what will happen, something I do surprisingly often because it is very powerful. Line length guide lines makes sense for me as a visual indicator of what will wrap when I hit the max lines per file. They are also nice ways to gauge when you are nesting too deep or making overly complicated expressions. Max line length allows you to do nice things with window management and diff tool layout and not spend forever moving around to see the text. I am a convert after thinking it didn't matter. Now it being 80 characters is arbitrary but so would almost any other number be.
