If Hive is going back up and gains popularity, the unique name thing must be resolved because if a big bunch of new users are trying to create their account but have difficulty on choosing a name because someone inactive already took it years ago, or worse because of bots taking every name possible, that's a problem.
At that point someone must take responsibility for deleting accounts
Deleting accounts is not so simple as it would require changes to the blockchain logic. That is why ownership is so valuable.
