In print, full justification of text is done by more than just varying word spacing. It also involves varying tracking (letter spacing) on per-line basis, hyphenation and even very subtle character geometry adjustments.

Typesetting software does a lot of that magic automatically and further allows easy manual adjustments to make the copy look even and readable without awkward spacing, “corridors” etc. Browser handling and latest CSS capabilities don’t even come close.

Having studied typography and worked in typesetting, I can’t imagine using full justification of body copy on the web.
