I completely agree with you, although I am not a commercial producer and would never do so. I build for myself; one could never charge enough for a model that may take 90 days to make.
In fact, even writing about our community is fraught with difficulty if one were trying to make a living.I essentially spent a lifetime from the late 1940s to recently to build and gather information about naval ship models of WW II for my recent book on that subject. So far, I have received about $1,000. for it. As a magazine published, we frequently pay an author almost that amount for an article that is only 8 p., vs my book of 160 pages. Since the publication of my book, I have almost stopped all naval ship model building, partly the result of the passing of my wife and sister. But I did buy one 3D printed model from an excellent German producer, because I wanted to have a state of the art 3D model vs an early example. The German model cost close to $200., which I think is a sum that would be hard to sustain in the long run, but I understand the labor that was put into this model.
