Points 2 and 3 seem like they could contradict each other. Wouldn't a tiny amount of power for you equate to a much larger amount of power at the radiation's source?

No. The transfer is inefficient because the vast majority of the transmitted power is dissipated in the environment as heat.

The transmitter cannot tell if switch the receiver on and off.
