Oh, man.
When it comes to my natural reaction to this, the words 'strong and visceral' doesn't even do justice.
It took me a really long time to understand why I had such a deep-seated loathing for phrases like that. Think of some absurd scenario where someone asks you to cause harm to yourself, so they can benefit in some way, and that's how I would respond. I basically translated these requests to something like, "can't you just shoot yourself in the foot, so I can sell your toes?" and reacted accordingly.
This post provides some good examples -- explained in a much more objective and rational manner than I've been able to -- of the cost, and why this bothered me so much. In general though, if engineers have to spend a lot of time mitigating "can't you just...?" then I think it may point to a more systemic problem in the organization. Namely, the business units are so disconnected from engineering they don't even realize the costs of what they're asking for, and the engineers are so disconnected that they reap zero benefit from whatever business goal is going to be accomplished by this.
I'm actually okay with shooting myself in the foot to sell my toes every once in awhile. I just don't want to do it if everyone else is going to make money from selling my toes except me, and they don't care about giving me time to rebuild my foot afterwards.
