An LED (or photodiode used as one) is a fairly simplistic device compared to an assembled receiver / transmitter. Just like you can burn gasoline in a car but you can’t push a car to turn the engine to make gasoline - it’s a complex system that really only works one way.
Nothing gets burned or otherwise destroyed when receiving EM radiation via a dish and converted it into electricity via a receiver.
Sure, the amplification stage of the process likely works only one way, and should be replaced in order to send something.
The one way process of burning oil to generate heat seems much more primitive than the energy conversion offered by a diode, TBH.
You can push or tow an electric car and charge their batteries. Because electric motors are also generators.
Even with your simplistic fossil fuel car in your example the alternator within can also be used as a motor.
