I think that it does, to some degree, in order to fulfill some of the promises that proponents claim will be delivered in the near future. There are ceaseless calls by BTC advocates for retailers of all kinds to accept bitcoin payments. For this to happen on a large enough scale there needs to be distributed demand by a great number of consumers, not frequent demands by a few edge cases.
I say that's the minority of the BTC users claiming that widespread adoption will happen.
But Bitcoin is already useful as it is, it doesn't need any more use cases, they just may emerge naturally.
