Pricing neutrality is hard to enforce and can lead to price inflation (c.f. interchange), but we'd be game for something along these lines. Part of Stripe's raison d'être is making pretty advanced payment infrastructure — only available prior to those with considerable means and past experience — available to anyone. We're obviously not there yet (witness the limited number of countries, payouts only being available in the US for now) but that's where we're trying to get to.
