Every time I hear this sentiment expressed I wonder about the speaker's familiarity with history and economics. The labor theory of value is almost a thousand years old and has been pretty thoroughly discredited for nearly the same amount of time. History is full of artisans who discovered just how much they overestimated the value of their skill only after someone came along and found a way to do the same thing more efficiently. I wonder how many tears were shed for the buggy whip craftsmen? The argument that this is different because this is art doesn't work either, because the endeavor's value is regularly quantified in USD - despite attempts to frame it as a non-commercial, almost spiritual, activity.
