The writing has been on the wall for decades. Images are losing value because millions upon millions are created every hour of every day. However, some of those images are remarkable and unique. People can make a lot of money if you happen to be the copyright holder of these images.
An example I like to give is the photographs Gary Rosenquist captured of Mt. St. Helens exploding and the side of the mountain sliding away. Nobody else captured this sequence. Not even close. These images make substantial licensing fees to this day.
I've long been fascinated by the fact that a camera can capture subjects the human eye cannot properly perceive. It just so happens that this obsession has led me to create images that are hard to imitate. I feel no guilt in charging fees for my images. I feel no guilt about pursuing people who have stolen my images for their own projects.
If you are photographing bald eagles with an American flag in the background or frosty fall leaves artfully arranged on the ground - I agree with the gist of this thread - these images are worth practically nothing. But this not universally true for all images.
