Ok, let's say someone proposes you to maintain either A or B, giving you 10.000$ per year. You have the right to choose one of the two. He tells you that the only info he can give you is the lines of code of each program.(think of it as a thought experiment.) If you say, I don't care to know - it's meaningless. you lose the chance to make 10.000$ per year by maintaining a toy application of 20 lines. Even worse if you say, I just need the 10.000$ and choose B randomly.

I mean, at least one info you get is that A is a toy application and B is a big program. Might be big because it's full of useless sh*t, but still it's big and this IS some information.
