> Variability in system fonts means that getting consistent paragraph and header widths and spacing is impossible.

Everyone is on different screen types. From desktop to mobile, different OS, low to high DPI, different resolutions to screen size (1080p on 21in monitor vs 27in monitor), different font sizes, different brightness/colors/contrasts. Most designers I have worked with have never looked at the site on different kinds of screens. Most designers only care about how it looks on mac.

Windows render font differently compare to Mac/Android. Chrome on windows renders font differently compare to Firefox.

You will never be able to render your site perfectly on all the devices.
