> You realize you're arguing for a monopoly, right?

Right! Like all the other monopolies that governments already have: public security (police and courts of law), external security (armed forces), public healthcare in many civilized countries, inspection of health regulations and consumer safety, monetary policy, etc.

> you trust your government not to ever be incompetent

Oh, I don't. But Apple, Visa, Mastercard and Google Pay aren't very "competent" either.

> history has proven that over the long term

History has proven that privatization of many of government monopolies are disastrous: Roman generals making private armies and destroying the Republic, abuse of forced labor from inmates in private prisons, exorbitant fees from payment providers (Visa, Mastercard), food dangerous for public consumption because the governments didn't inspect them, etc.
