why do people feel the need to buy expensive cable

Blah blah. Blind test. Some can’t tell some can tell. You have to have the ear. Or more importantly your own ear 

We don't feel the need to buy expensive cables, we feel the need to improve our system.

It's analogous to going to a hardware store and asking for a 1/4 inch drill bit. What you want is a 1/4 inch hole.

It doesn’t matter whether the information carried by HDMI cables is electrical pulses or rabbits. They are still audio and video signals. You know, like digital satellite signals, they are audio and video signals. I didn’t say they were analog signals.  The signal, whether the information is digital or analog is an electromagnetic wave. As such it’s subject to the same rules as any signal traveling through any cable or wire, e.g., purity and construction of conductor, purity and construction of connectors, dielectric material, susceptibility to RF, and “directionality” of the wire. That’s why Audioquest “controls directionality” of their high end HDMI cables, like the Carbon I use, as well as all of their other high end cables and power cords. It’s not a commie plot or an elaborate trick to fool gullible rich kids.
