I'm not disputing the case for low efficiency, for a single 
device,  but what if there were, say, 20 or 30 of those devices 
within the field?"

   If there were the transfer to each one would have an efficiency 
determined by its unique coupling to the "transmitter".  If they were 
separated from each other by enough that there was no mutual coupling 
between them [the receivers] then the total power would be the sum of 
the individual powers.
