Unfortunately, any loss is still a loss and will reduce total energy
available to do other things. Talking about "reactive losses",
how about energy lost to stray coupling to other objects? For
example, has anyone looked into losses due to coupling of the
primary to a good earth ground as a function of primary distance
above ground? Is this negligible?

Actually, to disprove something only requires a single counter example.
The person disproving something has the easy job in that sense.
