This has come up so many times before, e.g. https://forum.inaturalist.org/t/removing-homo-sapiens-from-reportable-taxa/2137 and with the same kinds of arguments like “this serves no purpose,” too.
Inaturalist is a social network for better or worse. Humans are part of it. People post human observations for entirely their own reasons and the overwhelming majority are benign. Leave the human observations alone, and deal with abuses on a case by case basis - just as with any other observation.
