Not necessarily relevant. I read wedrifid's comment as being less about fooming per se and more about what I might describe as the virtue of munchkinism: taking advantages available to you even when they conflict with implicit understandings about your role in life.

Exactly.

We could debate to what extent that's a core or necessary rational virtue, but I don't think it's very debatable that it is a rational virtue.

It's not core or necessary unless, say, the aliens with superior technology and the evil gods are trying to kill you.
