Agreed. For the most part, going to church is not economically rational. For the most part, having children is not economically rational. For the most part, being monogamous to one's spouse is not economically rational. For the most part, patriotism to one's country is not economically rational.
In a slightly different sense, going to space, or colonizing Mars, would all be economically irrational.
I'm wary of a definition of "rational" that tends take all of the things that humans hold dear, and declares much of it "irrational".
