People want to get paid. Most people will take most forms of payment if it gets them a sale that they wouldn't otherwise get. There's a cost, of course, to supporting different modes of payment, but if the increased business outweighs the cost, most businesses will take payment in that form. They're there to get paid, not to champion one method of payment.

I note, however, that in your first paragraph you dismiss the "one true payment system", and in your second, you pretty much advocate credit cards as that one true system.
