The comment by meric above seemed to be making a claim ("If there's positive (accounting) profit, it's worth doing!") about the general case, in which case opportunity cost is an important element.
If the claim was meant to be narrowly about this particular situation, then I still think a note that opportunity cost is likely to be low is an important piece of the analysis.
I never said (and did not mean to imply, and don't think I did) that including it would change the conclusion - just that omitting it left the argument incomplete.
