There are two ways to get a giant pool of people using your payment system: start with payments and then get giant, or start with a giant pool of users and then add payments.
In the first case you'd have to start with a tiny, specialized payments market that you could then expand. The second case would be Facebook creating their own credit card system. Which they could probably do.
I'd recommend starting with a specialized payments market. That's how credit cards themselves got started. And you can't create Facebooks for the asking.
