Why? I mean, security is always defence-in-depth thing, a think that consists of multiple layers, etc. If you would have left out the "part of" words, then yeah, implying that NAT is the only defense, that strategy must be thrown out of the window. By the way, ~20 years ago, when ISP just gave public IP and that was directly hooked to PC... yeah, got bitten by some random script on internet that just deleted my files via SMB thanks to how insecure windows configuration was. Was grateful when router was my defense :) Not that something important was there for a kid, but credit goes to... NAT. I think that may have been the time when I learned something about open shares.
