If you spoof GPS, you can have all the redundancies in the world, they’ll all agree over the spoofed data. There are videos of resulting egpws misfires [1] already. Also, (enhanced) GPS is also used to recalibrate inertial navigation to keep the system as accurate as possible during the progression of the flight, just saying…
