I'm only interpreting here (not judging). But I think s/he means you're spending a lot of time justifying the position that expediency is what's important, which is ironic.

I see. I gave the explanation because I experienced it and understand where it comes from. I am not particularly affluent, and therefore I often need to make the 'best for the buck' decisions, that also includes buying books and whatnot. I know that had I been affluent, I'd spent more on my hobbies over minmaxing.
