This topic has wandered far afield from HCB's favorite lens, but it's too juicy not to continue..
Back when I was in Art School (another topic ripe with possibilities!), I had one instructor who took a dim view of the "art world", a milieu that has only increased in insanity since that time in the seventies. His view, perhaps a bit Manichaean, was that there were two categories of people involved with artmaking: those who needed to make art, and those who needed to be Artists (with a capital "A"). Those who needed to make art were self-motivated, their compulsion to make art fueled by a desire to know the world, and themselves, better. The Artists were motivated by the permissions granted by their status, the opportunity to live outside societal norms, to act out their rebellion, to challenge the world. Theirs was a mode of being brought into existence by the nineteenth century invention of the avant-garde as an ongoing phenomenon.
Now, I don't know that this dualism is quite true; I think it's more a question of two opposite poles on a spectrum. But it does give us one valuable tool for understanding and critiquing a body of work. Examples: Vivian Maier at one end, someone who, to the best of my knowledge, remained completely unknown during her lifetime, but was utterly devoted to her work. At the other end, think Mapplethorpe, star-f***er extroadinaire, hob-nobbing at the Chelsea with the aristocracy of New York's demimonde and the celebrity fashionistas of his day. (I think it's obvious whose work I think has more value and staying power.) Then somewhere in the middle, perhaps, Weston; certainly an artist who lived for his work, but also one who was caught up in the conventional Bohemianism of his milieu, to the detriment of his long-suffering family and sometimes, I feel, his work.
So, it's the old question: are you in it for the love, or the money? A gross oversimplification, of course, and the real question is, how does one navigate between those two (possibly conflicting) poles and conduct a career, and a life, with integrity? I don't pretend to have an answer, and, really, it can only be decided by each individual.
