Because wood left wet will grow things that likely won't contribute to flavor.
I use chips only if I have them. By choice I use chunks for both grilling and smoking. Both chunks and chips will light when dropped on hot coals but closing up the cooker starves them of oxygen and puts the flame out, resulting in smoke. I see no benefit to soaking the wood.
