That's a lot of Humanoids

Yesterday I was working on a list of humanoid (and folk some are centaurs) from my notes, classic D&D sources, and current OSR sources. I might make a more useful version of this list some day but here for now are the names.  I'm sure I have omitted many and may have effectively duplicated the same one with different names in different versions of game books.  I ended up with 200 humanoids that could have their own civilizations or be part of another with jobs and occupations, a few faeries were bumped as were a few tougher solo monsters that aren't really part of a society.

That's a heap of humanoids/folk and it could surely grow more so by straying into the elemental and outer planes and d20/3e era monster books. Most of the top of the list is from my notes including stuff "borrowed" from elfmaids&octopi and renamed, classic D&D humanoids, Fiend Folio, Blood & Treasure Monster book (1st edition), The Complete Tome of Horrors, and others.
I just have to wonder: why so many? Is it because the role of humanoids has changed over the years, the need to provide some new eye candy ? They are all essentially someone else with a club that has stuff you can use and possibly talk to before you take said stuff by force or trickery.
I myself can't stop creating them and know of a few more OSR sources that would likely allow me to add in even more. Why do we need so many goblins, wildmen, and trolls scampering in the darkness?
