Busses aren't for safety. Seatbelts and airbags and etc are. Busses are just for moving large numbers of people around efficiently.
And yet statistically I'm safer on a bus. Therefore it's reasonable to ride the bus "for safety".
I would phrase it as: NAT accidentally "breaks" or "makes harder/impossible" something which yields increased security, under some circumstances.
It doesn't though. NAT edits your outbound connections to appear to come from the router's IP; it doesn't do anything to make inbound connections harder.
If you don't initiate a corresponding outbound connection first then any attempt at an inbound connection will be dropped (unless you have a DMZ configured ofc). The router literally can't forward the traffic because it doesn't know where it should go.
