Not sure I agree with you here (or I at least don't understand you). 
Font expansion creates more readable paragraphs by producing lines with 
smaller \badness -- surely that's an advantage even on screen? Where 
does the nonsense come from? (Distorted glyphs? Reading PDF on screen 
in the first place?)
