Not everything is a competition. You can believe both are wrong.
Make silicons, do nuke tests, operate heavy machineries, indulge in vehicle races, in satellite scale cylinders up there in heliocentric orbits, and if anything goes wrong in one of them, just throw it out of the system or into the Sun, to whichever preferred.
That was the future that the humanity envisioned in the 60s-70s, that we stopped following almost altogether(due to radiation hazard and lift capacity problems with assumed manufacturing on Earth surface). We should get back to that.
There seems to be a pervasive belief that we can just eject huge quantities of mass from the very strong, very isolated gravitational well we are bound to. To say nothing of the possibility of building such a cylinder, the realities and consequences of the situation are far more dangerous than people yet consider.
I make this point while recognizing that I agree national security has acceptable carbon footprint costs, while at the same time not liking arguments in support of that cost based not the premise that other policies are worse.
