I'm going to revisit the original premise and put forward the most basic (and essentially important) of questions: why should HBD exist in the first place?

I can think of reasons why it shouldn't exist, in fact, between us all, I think we could make a long list. But why even bother with that until we first have an argument for why it should exist? What needs does HBD satisfy (that already aren't met by dozens of others already - only a couple of which are really successful - and by fiat itself!)? What value added does HBD give us?
