How does wikipedia work? How does language work? Linguists have firmly determined that it does not work by a coterie of elites handing down decisions about correctness, regardless of what france pretends their "immortels" do.

That also doesn't mean "anything goes" either, obviously, since we do clearly speak a mutually comprehensible dialect through no intentional coordination. It's an interesting subject! You could stand to have some curiosity about its actual mechanics, there's a lot to be learned that is invisible to you if you've already decided how it should work.
