If one decrees before the first napkin drawing that Reliability Is More
Important Than Performsnce, and then walks one's talk, it is entirely
credible to talk about a three stage system that could deliver a
few hundred kg to LEO for a few million dollars with a crew safety record
of 99.99%. Vehicle reliability would be lower than that, with survivable
failure modes. Dispatch reliability would be lower yet, but better than
current ELV practice.
Sorry to be vague, but I don't want to step on XCOR's or Agile's toes.

It would be good if you'd explain why you think the *physics* doesn't
permit this.

This is why fault tolerance is more challenging in the case of a launch
vehicle when compared to aircraft.
It's a matter of physics.
