It's like the moon rocket. At any time we could have restarted that program from scratch and run it again, but what would the point be? We don't have the direct ability to make one but we have the ability to gain the ability to make one.

I don't think it's like that at all. I bet you could build a perfectly serviceable replacement at home without needing to spin up any special manufacturing equipment, using off-the-shelf components.
