RE: I think I should have said...

While what you say is technically correct, it glosses over the basic idea that the inductance has more to do with the characteristics of the drive impedance and not the value of the reflected load.

Taken to the extreme by your argument, a plate choke would need infinite inductance to match the reflected load. So would a line out transformer driving the grid of a tube. This opens up the whole large signal vs small signal can of worms which simply confuses the underlying concept. I think we can all accept that for a given tube, the more current that needs to be delivered to the load, the more inductance is needed. The idea that doubling the load requires 2X the inductance puts far too much emphasis in a FOM that isn't universally applicable.
