I mean, I think, Occam’s Razor, he’s got a rudimentary, non-functioning facsimile of a digestive tract that takes all the food he mashes up in his mouth and pushes out his poop-shoot when he wants to empty himself. That would allow him to have a mostly human-like eating experience, which would aid him in his quest to be more human. I think Soong would have argued pooping is integral to the human experience (After all, he made Data able to pointless eat, drink, and fuck. Why draw the line there?), but even if he didn’t, having Data lean over a sink and regurgitate everything he swallowed at the end if the day feels pretty inhuman.
Sure, but it seems weird to program that in. Part of his journey to becoming more human should be developing his own body dysmorphia, not having one assigned to him.
