So, it appears that doubling the length of a short antenna captures
about
3.6 times the signal.

And, therefore, by the reciprocity characteristic, the short antenna is
an inefficient radiator?

I will answer your question if you can tell me the efficiency of an
isotropic radiator.

As for all religion, an isotropic radiator is make-believe, and like all
religions, you can make up whatever you choose to be your story.
