It's predictable that every Stripe-related post will have non-Americans asking when Stripe is coming to their country.
Less common or nonexistent are the comments where someone posts a link to the beta Stripe clone they are building to launch in their country. Do it, at worst you'll be acquisition bait.
Most countries don't have the same facilities as the US for creating payment-related businesses (financing, engineers with expertise in the field, close to the backbone visa/mc/banks, bureaucracy). It's probably much easier for an established company to bully their way in, than for one to grow locally.
That said, there are no excuses for trying, and there are exceptions; I sure hope they succeed. I'd love to work in an area as disruptive as this.
