Modern fonts have extra stuff to make rendering better.
Like hinting, which changes subpixel representations.
Without those, you wouldn’t like the look of something like a character with a height of 10px on a 1080p display and would have to use way higher DPI stuff, with characters taking more pixels.
Won’t be unusable though. Automatically done anti-aliasing tends to be good enough too.
