Also, gear is fun. I think there are a lot of us (certainly I include myself) for which exploring the tools is a significant pleasure in itself. That activity isn't the same as artistic photography, but there's no reason they can't coexist, is there?
Certainly not. The whole history of photography as a medium whether it be as art, profession, document, hobby, gear lust, etc has been one of people interested in making images and those who love equipment. The breadth and choice of equipment we have available to us has always been driven by enthusiasts who love gear. We all benefit from this as it creates a market that manufacturers want to exploit.
Probably the smallest group of photographers is those who are only interested in making images. Thereafter comes those who like making images but equally like playing with the gear and the largest group of people are made up of those who either use cameras to record their lives (hence the explosion in phone cameras) and those who simply love getting the latest piece of gear.
Whatever motivates people to take up photography is irrelevant if they enjoy what they are doing. I do not understand the craze for using cameras such as Holgas, etc but I am very pleased that, in using film cameras, these people help to keep film photography alive and that I can still buy the materials I want for my photography.
The main point of the OP was, I think, that too many people who started out wanting to concentrate on making images get wrapped up in all the gear and technical options available to the detriment of making good photographs. I do not think anyone would seriously say that someone MUST only use one camera, lens, film, developer, paper for all applications of photography but, rather, that for a particular project, way of working, area of interest using only one camera, film, developer, paper can really sharpen your vision. If you do it long enough, you never 'miss' an image because of having the wrong lens, etc simply because you are so concentrated on what images you can make with your chosen combo and see them to the exclusion of anything else.
Certainly, for my work, using one camera, lens, film, developer paper for the past 12 years has resulted in me achieving a very high 'success' rate per film of images that I will print for exhibitions. It is not a solution for everyone and should not be interpreted as such. I have recently got a new camera (of the same format as my current combo) with a slightly longer lens and plan to use this over the coming months to see how it may or may not affect the images I choose to make. This will be a process of learning to see my chosen subject in a slightly different way. If I like the results then I will sell my current camera. If, after so many years being comfortable with my current combo, I find that the new camera is getting in the way of me achieving the images that I want, then the newer one will be sold.
