An Earth/Mars economy will have nothing to do with the settlement or development of Mars. Of course, settling Mars will have benefits for the Earth economy as new technologies are developed, but a Mars/Earth economy isn't going to happen anytime soon, and it shouldn't be a requisite for going.

Why would you want to export methane?

Mars has resources and gravity that will be of use to those living there. That's the point.
