It's not just a matter of building a pipeline and shipping the gas. As Art mentioned, the gas has be conditioned to make it a useable product and that takes an expensive plant. I was tangentially involved in some high level discussions about the plant and for the full size line they were talking about a $10 billion plant.
The problem we have with such a large state and such a small population is economy of scale. You cut the throughput of the line to 1/10th or 1/100th and cost doesn't drop at anywhere near the same rate.
