Paraterraforming vs. terraforming the Moon and Mars

It should be, but, the 'economics' situation behind capitalism says that
there'll be no investment (aside from enthusiasts like us) in space unless
it can be shown that the investors can make a good return on their
investment. SPS is one of the shorter term avenues to ROI because it's
mostly off the shelf tech and ther's always a market for energy. Also, the
construction of a halo of SPSs would necessitate getting a lot of people
into space and the construction of at least temporary habs for them during
the assembly and placement process. Part of the plusses enumerated to
O'bama in the proposal to his transition team was the fact that thousands
would be (newly) employed in both the space end and the ground receiving
station construction.
