I think economics provides useful tools for talking about and evaluating this stuff, too, but I think it's pretty evident that you can optimize for anything you like and get different results.

If you choose to put yourself behind a NAT that's possibly good for you (although I think it's bad for you over the longer term) and always bad for the people who want to reach you. > There certainly are cases where it's appropriate for the IETF to say > that something users want to do is not OK.
