It's all about gatekeeping the skill, time, and budget floor and propping up the wall between "producers" and "consumers". I worked hard to get where I am, therefore it shouldn't be made easier. I worked hard to make $20/hour, therefore we shouldn't raise the minimum wage. Etc.
The reason there aren't legions and legions of programmers protesting AI on twitter is because programmers are accustomed to change and we've learned to embrace it, yet every time there's a technology that changes how art is made (cameras, digital painting, 3d rendering, even pre-made pigments), there are a group of artists who flip their shit and say that the new technology is going to kill creativity and ruin art as we know it, then fifty years later all of the things that those people insisted are "not art" are in museums and art history books.
