If we're talking tangible, real-world threats in existing ISPs, then NAT is doing nothing to protect you. In fact it's doing the exact opposite, because without NAT you wouldn't be able to connect out from your network.

Even if you want to ignore the fact that most attacks arrive via outbound connections and restrict the discussion to just inbound ones... remove NAT and the exact same set of people that could connect to you before can still connect to you, so it's doing nothing for your inbound connections.
