I think he is implying that that is neutral, not a loss. It is opportunity cost.

Is the opportunity cost of someone who has never programmed an iOS app before $2500/day as an iOS dev?

Maybe in some analyses, but that’s not where I’d estimate it. If they’re turning down other $300/hr work, sure, but that’s not how I read the account.
