Good CSS lessens download times, by simplifying html. CSS adds structure to html-code, it helps me to write greasemonkey scripts or to block annoying (wasting space or blinking) parts of page with uBlock.

There are no good reasons for me to allow page to use fonts except those I explicitly installed into my system.
