I thought it was pretty clear that the implied irrational part of it is the opportunity cost of choosing your hometown, not the actual attachment itself.
If I'm a brilliant mathematician or a world-class athlete and I choose Kansas over Cambridge/Boston, then yeah, plenty of people are going to think that my attachment to Kansas is making me act irrationally. I don't think they lack a "modicum of intelligence" because of that thought.
There are obviously exceptions where your choice of location doesn't matter, but if you're a high performer then it frequently does (with the obvious notable exceptions e.g. Prince).
[EDIT: I originally just had a quip about not being a sports fan, but I thought you deserved a real reply.]
