Just to give a common counterexample, the SEPA system allows me to trivially transmit money to anyone in the eurozone, for a considerable portion of them (including everyone in my country) in seconds, completely free of charge and involvement of any third party except my and their bank. Cash App, Venmo and comparable services basically don't exist in the EU, because the governments stimulated and mandated large scale interoperable digital infrastructure.
