If someone wants a script that does a very simple task that could go with 10 to 20 lines of code, why load a module??

Because, in general, they aren't asking for a 10 or 20 line script. They are STARTING with a 10 or 20 line script. The 2-4 line script with a module generally puts them on the road to doing what they really want, shorter, safer, and already working.

And no, I don't think that stumbling around in the dark is a good way to get the feel for the layout of a house, turn the lights on and look around. You will learn more seeing how it is done right than you will stabbing about.
