Who said anything about ignoring it? It is a tangential question.

  Thread title: "Why do people put on differing amounts of weight?" "I'm still pretty sure that calories-in/calories-out theory is more-or-less correct." Counting calories-in as calories absorbed is not exactly tangential, it may very well be the essence of the conversation.

    It's tangential because, despite being at best an approximation, calories in is still a measure that can be used to reduce intake. It might take experimentation to find the limits for you. It's quite simple: if you are gaining weight, eat less. The variation between calories marked and calories absorbed is not great enough to fundamentally matter.
