OP,
The paper/book that you posted is right where to start with a no BS explanation of this topic. If after reading even half of this well written and serious paper, you still don't want or get the reason for the need to care for albums in a specific manner then that is your choice. It really just amounts to physics on a small scale. When you see the photos of the interface between the stylus and groove, and the force presented during play, perhaps then this will all make good sense.
