But even if that was the case, is there any value for a receiver to be receiving those? Surely those messages would be picked up by a receiver closer to the transmitter anyway. I think the value in spoofing rejection is greater than the probability of a transmission reflecting from beyond the horizon and not being already being picked up by a local receiver.

Yes, radio propagation is an entire academic field to be studied :) In addition, if you have enough receivers you can use that to run something called MLAT [1] to also pick up GA aircraft that just have a transponder but no GPS. The more the merrier. [1] https://adsbx.discourse.group/t/multilateration-mlat-how-it-works-and-why-you-should-care/325 https://adsbx.discourse.group/t/multilateration-mlat-how-it-...
