One of the best discussions of this topic is to be found in Chapter 16 -- "Free Markets Versus Regulation" of George Soros's Book "The Alchemy of Finance.' This is available from Amazon in Paper back for not much money. I can't recommend this ~400 page work too highly to anyone who really desires to understand financial markets. Soros is not the clearest writer. One gets the impression he his arguing with himself as he writes. He apparently wrote this particular book for himself. Its real purpose seems to have been to help him clarify his own thinking. Most of us, including our former Fed Chair, Paul Volcker, have had to read "Alchemy" two, or even three, times to get the most from it. One person who did exactly that, and paid attention too!, is Stanley Druckenmiller, who Soros hired ~1988 to run the Quantum fund.
You quoted McConnell's
"Microeconomics by Campbell McConnell - Part 1 Introduction to Economics and the Economy,"
"Although government ownership of resources and capital in China is still extensive, the nation has increasingly relied on free markets to organize and coordinate its economy."
Do you think that McConnell believes that pure free markets exist?
I have mentioned that when one reads the term "Free Markets" it is critical to remain aware that 1) The term may not be being used as you think, because there are (at least) two very different meanings attached to the term "Free Markets". I mentioned this in an earlier post. For that reason, Economists generally shy aware from use of this term except in loose comparisons, such as McConnell's remark above. They might prefer to use the term "laissez faire," because this is less ambiguous. Laissez fair, in economics, means the absence of government regulation and government interference with business. And 2) When I say "Free Markets do not exist in the macroeconomic world," I am of course meaning
pure Free Markets, and not just hit and miss occurrence of some elements of a free market. And as previously explained, I am using the term "Free Markets" to mean "Free Markets" in the layman's sense of that term. The Layman almost always, by use of the term "Free Market," means a market where participants (buyers and sellers) are free to participate on exactly equal terms in an atmosphere of perfect competition where neither participants nor the State has erected any barriers that would bias the market in favor of buyers or sellers.
I am confident that you will agree that
these kinds of markets do not exist. But that raises what, to me, is an interesting question: "Could they exist?" To answer this question, you might read Soros. But I will play the spoiler here, for which I apologize, and give you the answer: "They can not exist for fundamental reasons."
Once we understand this, the question of whether "Free Markets" exist, becomes moot. If they can't exist, then it follows they don't!
Even if I were to use the term "Free Markets" in the sense that economists use it to mean a market resulting from laissez faire business practice, it would still be true that "Free Markets" don't exist.
There are two different economic worlds (perhaps more) the black and white world that exits only in theoretical models described in textbooks such as Mankiw's, which I own, and McConnel's, which I probably also own but have lost track of, and the gray, everyday, world that really does exist. In your quote of McConnell he means to refer to China's economic policy that is increasingly moving away from a much higher degree of State control and in the direction of the ideal, but mythical, laissez faire, "free market". He doesn't mean, nor would he want you to interpret his remark as meaning that a pure, true free market actually exists. That's not what he said, and not what he means. That's something you have inferred.
Similarly Mankiw's statement must not be interpreted to mean that free markets exist, but rather that economists advocate the
relative absence of government interference in markets. Economists believe (most of them) that the
relative absence of government interference will produce markets that behave more like the ideal model.
But we must never forget that the ideal model takes no account of , i.e., it ignores, the morass of cartels and monopolies, that pure laissez faire markets would quickly deteriorate into. We have approached, to a considerable degree, laissez faire markets during various periods of the past, and indeed these largely unregulated markets deteriorated rapidly.
So what are economies in the real world like? Real world economies are always a mix of two extremes. Each extreme represents a polar opposite in economic thinking. In one, the optimum allocation of resources is believed to be achieved by tight regulation of markets by the State. The Marxian economy approaches, but does not reach, this extreme. In the other extreme, their is no regulation at all, pure laissez faire business practice pertains, and that, it is believed, will produces the optimum allocation of resources.
These two extremes, in their pure form, are models based on two different schools of economic thought. Real markets, the ones that exist in practice, always incorporate a mix of characteristics of these two economic extremes. The debate is over the degree and type of regulation that will best move us toward the optimum,
while recognizing that the optimum is not attainable. We find this expressed in the final, two-sentence paragraph of Chapter 16 -- "Free Markets Versus Regulation" in Soros's "Alchemy..., where Soros writes, (
ca. 1986)
"After nearly half a century of what now appears as excessive regulation, we have been moving towards excessive deregulation. The sooner we recognize that some kind of regulation is necessary in order to maintain stability, the better our chances of preserving the benefits of a nearly free market system."**
The bolding and underlining are mine of course. Soros is under no delusions that the optimum allocation of resources is attainable. He knows it isn't. And of course he knows that ideal, pure "Free Markets", i.e. those that don't quickly deteriorate into cartels and monopolies, or those that I refer to when I use that term, are equally unattainable. That's why he is careful to qualify the term "Free Market" by adding
"nearly". But I would say
"nearly" is a little too optimistic. I think we will always remain somewhat further from optimum than we might otherwise achieve if only our understanding could be improved and our natural inclination to embrace fallacy reduced.

** Soros penned this in the mid 1980s. His remark proved to be prophetic. While others were still extolling the virtues of the massive deregulation of the 1980s, Soros recognized that deregulation had
already gone too far. It would be another decade and a half before this would become widely recognized. In 2008-9 we experienced first hand a deregulation catastrophe. And now we seem to be in a period, once again, of excessive regulation.
