Solving world hunger with enzymes? Why not?

We have pills which give us enzymes, such as lactase, which allow us to digest certain sugars, such as lactose in dairy.  Why then is it that we cannot make a pill for cellulase, enabling people to digest the cellulose in plants and possible solving world hunger?  Does it have anything to do with the fact that it is never found naturally in the human body?

Because world hunger is not a food problem. 

It's a problem of delivery. Most of starving people and people who don't get enough nutrients, live in unreachable areas. Those areas can be unreachable due to natural caused (common in SE Asia, due to rainy season, etc.) or due to man-made problems (wars, other conflicts).

The reason scientists want to introduce Golden Rice in south east Asia countries (rice with Provitamin A) is because these areas are unreachable for most of the year, there is no where to keep food (it would be spoiled), etc. and not because we want to poison poor children with GM rice.
