I don't think the consumer use case is as important as most people think. At this point, it doesn't make sense for people to buy cryptocurrency just to spend it -- it's extremely volatile and usage is too low to justify interest from merchants.
People should continue using cryptocurrency as they see fit -- as a speculative investment, for P2P payments, for commerce, etc. Merchant adoption will come in time but it will always lag significantly behind user adoption. They don't have a strong incentive to accept Bitcoin payments until consumers demand it.
