I think the merchant should still be the one to dictate which payment providers can be used. The user can choose from those supported providers. The merchant is the one who needs to get paid and they are the one who needs to have a pre-established business relationship with each payment provider. (The user needs to establish a business relationship but they can do that on first purchase.) The only other alternative to payment provider discovery that I can think of is some kind of magic blockchain-like payment cloud :)
