People will use good gateway directly without the need to go through an obscured crypto-washed intermediary like Ripple.
The gateway is a part of all the Ripple system, and there isn't anything obscure in Ripple.
I come to the conclusion that maybe if someone isn't able to understand Ripple, he isn't also aware to how Bitcoin works.
If you claim to understand Ripple, show us a real use case and not some hypothetical example to articulate the benefits.
Illustrate how you can send 1,000,000 Yen from Japan to someone in US at the best USD conversion rate that is cheaper and faster way than existing options out there today. Proof it.
