The Repugnant Conclusion has always seemed straightforwardly and unobjectionably true to me. I've always been confused by its alleged repugnance, or why such an anodyne-seeming conclusion merits such a dramatic name.
This isn't like the other standard objections to utilitarianism. I'm not persuaded by concerns about utility monsters or trolley problems, but I feel the sting of those objections – they feel like bullets I need to bite. Whereas the Repugnant Conclusion just seems like a non-problem to me.
I say all this not to argue against concerns about the Repugnant Conclusion, but to motivate my question here. I'd like to have a better understanding of the intuitions that lead people to seeing this as such a serious problem, and whether I'm missing something that might cause me to put more weight on these sorts of concerns. I'm less interested in technical philosophical arguments here than in intuition pumps – simple thought experiments, or real-world scenarios, or related problems that might help me feel the sting of the objections a bit more.
