The idea that Donald Marron (who argues "we ought to allocate the initial property right to the person likely to care most about reclining... the person sitting behind") is wrong simply because the author has never had anyone attempt to negotiate with him is specious. If I spread out across two seats on a busy subway, I would probably also say I "rarely had anyone complain... and nobody has ever offered me money."
(I also find the whole tall-privilege angle interesting, especially given the vitriolic way he framed the debate on Twitter -- "The world favors the tall, yet they have the gall to whine about the one place (airplanes) where height costs them" -- but being 6'6" I'll leave that aside lest I be accused of advancing some sort of tall agenda.)
