It would likely make them worse since few loads could take its high G and thermal loads, hence exacerbating the fixed cost vrs low market demand issue that dominates launch costs.

Same way space Elevators would likely drive costs to orbit way up compared to rockets – (potentially tens or hundreds of times more with a similar market size).

Hunter believes he has the solution to some technical problems associated with launching a high velocity object in the lower atmosphere. There’s not much mention here on that problem.

But the military has deep pockets, so he may that problem handled.
