You're conflating properties of a payment processor like Visa, with properties of a currency. What's the equivalent of a charge back if I pay in cash for services that aren't rendered? It's called a "lawsuit", and there's no reason you couldn't use it if you paid with Bitcoin. With Bitcoin, unlike cash, there is also a public record that you did in fact pay, so the defendant couldn't lie and say you never paid when they just hid the cash under their mattress. Likewise, there's no reason a payment processor like Visa couldn't process payments in Bitcoin and provide fraud protection if that is something people want. Bitcoin isn't there yet, but neither was cash until about 50 years ago, out of thousands of years of usage.
