HN can't be a community without members. Disembodied comments are not community members. No one is required to use their real name here, but users need to have some consistent identity for others to relate to. Otherwise we might as well have no usernames and no community at all.
A disembodied-comment forum would be a different kind of site—perhaps an interesting one, but not Hacker News. You're free to find one or create one, but not to turn this one into that.
