It's not so complicated: if you want to earn money, you produce something that someone else is willing to spend money on. If you want to produce artwork, you do whatever you want to say, not what people want to hear. Sometimes people want to pay money for what you want to say.
The point is: good 'traders' in this game know how to do both, and, more importantly, stay aware what side of the line they're on at a given time.
