Though it is not often appreciated re SpaceX/NASA, I side on the "competition is good" side of this argument.

I don't think gov should act like a single consumer, instead they should err on the side of producing an ecosystem of solutions to spur an economy around the problem.

So, two is cheaper than one long term, I hope.

Becuase money isn't magic and that money going to a very unsuccessful company BlueOrigin is now not available for space suits, habs, surface operations and many other potentially useful things.
