Equanimity - if not a poetics, then what?

"'We all found it hard to imagine a system of poetic value not grounded in scarcity.' C'mon guys, you can do it."

Is this from the poet's or the reader's perspective? From the reader's perspective, any scarcity is highly artificial. What's scarce is not good poetry to read, but discernment, time, and knowledge of foreign languages. From the poet's point of view, the problem is finding readers, and hence the illusion of a certain scarcity is useful. That is to say, if a given poet is only one of two thousand equally worthwhile poets, why should any particular reader choose to read him or her? How can one distinguish oneself from the thousands?
