Because their structure is too complex to animate.
Watch any good cartoon and you will see that character designs are very simple. It makes sense, even if you have the most skilled artists int he world, the amount of work that would go on simply not making their faces explode is not worth it.
Characters are made of shapes, and they each have to obey and react to the movement of other parts. There's hierarchy of shapes and movement and when you have so many of them you are bound to make them lose shape.
Realism is also opposed to many principles of animation. You can't use exaggeration or stretch and squatch and poses become harder because of the less defined sillhouete.
