After all, paper (and PDF) is cheap. It is better to maximise readability than paper-cost-per-word.
I can see one reason which could have historic reasons. When you flip the pages with your hands, they will wear out more on the outer horizontal margins. If you make that margin wider there is less chance of corrupting the printed content. However that would not apply to online pages.
(Both of which also explain why the outer margins are larger than the inner margins.)
Grid systems have really helped the layout issue since then, although none of the ones in current use seem to be based on the golden mean.
edit: Sorry I think I'd accidentally clicked through to another page which did what I said above -http://roundedbygravity.com/colophon/
I tried to implement some of this in CSS, but here are the issues I had with it:
- there aren't left and right pages on web, so margins should be equal. Classical page layout means that the left margin, right margin, and the gap between the two pages is equal.
- there's no comfortable way to control line length in a fluid responsive layout, unless you have really obvious breakpoints.
- because long documents aren't broken into pages, the bottom part of the page runs off the bottom of the screen so there's not even a concept of page length on web
I still have more thinking to do, and so far I think the site that has done this best so far is medium.com
