I see what your saying. But a few things. The speculation is a relatively recent phenomena in bitcoin. There were always speculators, however since the new year it has exploded. You hear less about people producing items, starting online stores, or engaging in a more tangible economy. They are there and will continue to come into the fold (In my opinion).
To my mind speculation is just another iteration of the bitcoin story. It shows that btc is expanding into new markets and mindsets. Next could be the remittance market. That will bring a new subset of peers and new challenges. This experiment is just getting started.
