"[The market in digital goods] is huge and it's growing fast. Bitcoin allows us to take payments and not have to worry about chargebacks which have plagued virtual goods sales since the very beginning. Historically, to take a (generally) irreversible payment such as Western Union or a bank wire transfer, it meant exorbitant fees that made small transactions cost-prohibitive.
As you know, when you deliver a virtual item, you're left with no verifiable evidence that you've done so and it's very simple for the buyer to claim that they've never received it, or that their card was stolen, or that their child made the purchase without their permission. It's this not having to worry about chargebacks that allows us to store Bitcoin on behalf of our users and allow them to trade and cash out at any time. If we had to worry about deposits being reversed, there'd be no way we could allow users to make withdrawals. Bitcoin solves this problem."
This is why Bitcoin has fundamental value. It is
useful. Beyond the rhetoric, the political implications, the economic theorizing, the hyperbole... beyond all that, Bitcoin is
useful.
