No, not everyone is running UPnP. Maybe on most home networks, but that’s not the audience that even knows or cares about NAT.

I think this is where the disconnect is: the home users are precisely the ones being talked about, because they are the ones most likely to be treating NAT like it is a security system for their devices in the real world.
I've literally seen someone's ISP turn on IPv6, and then have their long-running VNC service compromised because they were just relying on NAT to hide their services.
