Ideally, humans should carefully steward the wild ecosystems left remaining on the planet in an effort to retain genetic and behavioral diversity until we can figure out how to use it (or not) properly.

Pragmatically, the species that are flourishing most at present (as measured by reproduction, range, and persistence) are those we've domesticated and come to appreciate or depend upon. For non-human species at present, its the old "if you can't beat 'em, join 'em."

We owe our current "success" as a species to being the best, most diverse mutualists on the planet. Asking humans to repress our domestication instinct is requesting that we relinquish an enormous evolutionary advantage that is probably hard-wired into our behavior at this point. I can't say you're wrong, but asking humans to stop taming things will be about as effective as asking legumes to stop nodulating.
