I'm not sure I understand how monopolies acquiring their competitors early on in order to be able to maintain their monopoly price works in practice. Wouldn't the eager gaze of startup founders looking to strike their first big score turn like the Eye of Sauron on any such industry? And all the monopoly profits that the monopolist stands to extract would in the medium run hit an equilibrium of zero when balanced against the extractions of the people it's forced to acquire?
