That whole argument flew out of the window the moment so-called "communities" (i.e. in this case, fake communities, or at best so-called 'virtual communities' that might perhaps be understood charitably as communities of practice) became something that's hosted in a random Internet-connected server, as opposed to real human bodies hanging out and cooperating out there in the real world. There is a real argument that CoC's should essentially be about in-person interactions, but that's not the argument you're making.
