You critique of point #2 is invalid because a Jet is a discrete system that requires considerable outside resources to keep working. It works by the same principles as a socialist economy funded by natural resources that acquire large amount of cash and other material support and resources simply by virtue of digging a hole in the ground and hauling stuff out of it.

A jet is not intended to be self-perpetuating.

Point 3 is an observation. I probably could have broken it into into two separate points for greater clarity.

I am still waiting on a working example in regards to point 4, that can operate with self sufficiency.
