"Einstein's Elevator -- is Einstein's equivalence of inertia & gravity logical?"

I don't believe so. The argument is that a gravitationally accelerating observer feels no force whereas an observer accelerating under their own power does but that's erroneous in my opinion. A gravitationally accelerated observer feels tidal force - the difference in gravitational strength over the length of the observer. That's exactly what an observer accelerating under their own power feels, if their entire length of the observer (in their direction of motion) were accelerated evenly they would feel no force.
