The mere addition paradox also manifests for a single person. Imagine the state you are in. Now imagine if it can be (subjectively) improved by some means (e.g. fame, company, drugs, ...). Keep going. Odds are, you would not find a maximum, not even a local one.

Hill climbing always finds a local maximum, but that might well look very disappointing, wasteful of effort, and downright stupid when compared to some smarter means of spending the effort on finding a way to live a better life.
