> That third party involved is my ISP which will see the packets anyway, even if NAT is not used.

The ISP doesn't meaningfully see packets as long as encryption is used. It sees stuff that if analyzes can be used to make guesses, but that's about it. I probably should have used a better term than "third party" but I was meaning services that collect data on everyone like Facebook, Twitter, etc. These services actually receive meaningful, trackable, surveillable data about you and they would not have to receive as much if NAT wasn't a thing.

Inside attacks are important. If you don't care about those, saying you like NAT because of any security benefit doesn't make sense.
