Oh, I know the reason, but that won't stop me from complaining. It's fun. I spread out the books when I can, but sometimes I can't. Like tipping porters generously when they help me wrangle my gear, I consider it part of the cost of doing this. Compared to the alternative (doing without whatever is in the bags), it's trivial.
