(Of course if you were spoofing ADS-B RF signals you wouldn't necessarily need to be anywhere near the spoofed locations. Just like with GPS spoofing.)

Surely the receiver would run plausibility checks on the received messages and reject spoofed locations that are physically impossible to receive by said receiver?

Wait until you hear about Sporadic-E or Aurora. RF is a weird place full of natural phenomena making the impossible very possible.
