Like Earth, the resources on Mars are at the bottom of a gravity well and lack the benefit of Earth's breathable atmosphere, massive infrastructure and ~7 Billion inhabitants. What, exactly, would you profit from by owning 250 miles of that? A business would do better to snag 1 mile of diamond-yielding tundra here instead. Want something valuable?

Right there you've identified a competitive advantage (low-cost of scarce resources) to satisfy a growing market which exists today.
