Paypal Europe have a banking license. The problem is regulation, or at least the interaction between strict KYC/AML regulations and a business model that allows basically anyone to accept electronic payments. Banks and money transmitters are substantially deputised to enforce a raft of laws regarding the conduct of their customers. Either you're choosy in who you accept as a customer, or you're liberal in who you accept as a customer but have a hair-trigger response to any transaction that looks even vaguely suspect. Any alternative strategy will eventually lead to jail time.
