A person could place 100 feet of extensions between two torque wrenches and when the torque reading on the one being turned reached say 150 Foot lbs you will have exactly the same reading on the other end no matter how many revolutions you have to turn it to wind up all the extensions. Now put an 800lb capable impact wrench on the end of those extensions and you'd be lucky to get a bolt much over finger tight just as you said. BUT The reason the impact wont work with long extensions is the impact wrench applies torque in spikes that last only a few degrees followed by zero applied torque for many degrees. The extensions do not change the total amount off energy being developed. But due to the springing they spread that force out over a longer time period. Since they make or destroy no energy as you said the peak torque must come down when the time it is applied goes up.

I agree, the impact wrench sits there and pulses and surges its energy output and each time it gets a hit the extensions flex/rotate a bit which absorbs energy but its returned when they flex back HOWEVER that flexing and return each time converts some of the input energy to heat instead of it all going to rotational torque......That's different then a straight dead pull on a breaker bar and once the extension reaches its elastic limit and turns/flexes no more, Id say torque in equal torque out after that PERHAPS, MAYBE LOL
