> Your average citizen gains nothing from adopting a currency that is highly volatile, concentrated in the hands of a few, and awful at completing everyday transactions.
Maybe, but those problems are not necessarily permanent, and it can be valuable without targeting the "average citizen." As a counterpoint to your "gains nothing" view, many "average citizens" used bitcoin for transactions in the early days, only to find out that holding some of their currency in bitcoin made them rich, so they did gain something. Even if that is only a small possibility, the possibility is still there.
