David -- I agree with what you say, but at the same time it's a statement of the obvious. There is a middle ground. Many people go out with cameras to record what they see, not necessarily to impose art upon it through careful composition, but still with the idea of a photo being 'pretty'. This is somewhat artistic and somewhat documentary, as opposed to technical photography which seeks purely to document.
In this regard, I don't separate macro photography from anything else. Your distinction is like the difference between a police mug shot and an artistic portrait. Different approach for different purposes.
