4. Energy expenditure

I share your skepticism about that. Basically this would have to carry twice as much fuel as the rockets that can't descend under control. And when we are talking about lifting to geosynchronous (as opposed to just going up a half mile for a photo op) the payload is already limited to about 3% of the total weight.

The control system is definitely cool and impressive, but Musk seems to have this "then the laws of physics suspend just for me" attitude with both this project and Tesla.
