Excellent point.

The 'standard' 300 dpi comes from the fact that that is the most resolution a perfect human eye can resolve at a distance of about one foot - i.e. someone with perfect sight could just about distinguish 150 dark/light line pars per inch with each one 1/300 inch wide--

Actually, you are describing someone with 20-20 vision, not perfect vision.  There are those, particularly if young, that can see rather better than 20-20.  They are good prospects for being pixel peepers.
