> every province does have its own government with some degree of autonomy That's not a federal system as generally understood. Generally, the distinction between a federal system and a unitary state with somewhat-autonomous subdivisions is that in a federal system, the powers of the subnational entities are constitutionally entrenched, whereas in a unitary state, the autonomy of a subnational division is at the will of the national government. The overwhelming majority of countries have some form of autonomous regional government, because it's impossible to run any sufficiently large country any other way, but the majority of countries are not federations.
