If only everyone shared the same use case :)
Maybe I have a server at home, with a locked cabinet and vibration sensors, that houses a server or two and they all use full disk encryption, but I still want to be able to reboot them without having to connect a physical keyboard to them. So no one has physical access, not even me, but I still want to be able to reboot them.
Or countless of other scenarios where it could be useful to be able to remotely unlock FDE.
That's not a counter-argument. You are protecting the physical access, and your threat model doesn't include someone willing to bypass your locks and sensors. (or it does and you just didn't go into those details.)
The argument was that physical access gives up the FDE key.
