Storytellers usually write their own campaigns and adventures... Also, the beginners adventures are supposed to help you learn the rules. The DM can modify them to include more diplomacy if he wishes to easily. Good DMs just use published adventures as a starting point for their own adventures, or as sources of ideas. Additionally, hack'n'slash adventures are easier to write and to play. They sell better, usually. A sad but true fact.
Descriptions and such go on pages of lined paper, not on the actual character sheet. There is no room for it there, and what is the point of printing out or photocopying pages of blank lines?
The rule books are meant to provide the basic platform from which to build the stories of your adventures. There are numerous campaign settings you can purchase that have lots of backstory type stuff in them, with much more detailed info on various races, rather than a listing of stats. Do you want the monster manual to be 8,000 pages long, or to just have a dozen creatures in it?
It is a game. In order to play a game, you need rules. This is what the core rulebooks (and supplemental ones) are. They provide the framework. They are not meant to provide endless stories to roleplay.
