If e.g. the government provided free healthcare for all...
That's a monopoly, chummer. One that funds itself by force, no less.
No, it isn't! You are free to provide healthcare for free or any price as a supplement or alternative to the public service. Most countries with a public health service have private alternatives for those who want to pay for it.
I see. So Standard Oil
wasn't a monopoly, then?
Standard Oil? What do you think Standard Oil and free public health care have in common?
You know a price scheme more "predatory" than free?
Did Standard Oil give away free oil? Free public health care will not benefit at all from being a monopoly. Quite the opposite.
Wait, I thought you said it wasn't a monopoly. Now you say it is, but it won't benefit.
Try and get your story straight, chief.
