Terms don't "exist" or not.
In academic economics, they certainly do or don't. If you're inventing your own concepts, define them. But what you've described is a concept well understood and defined academically - we call it perfect competition.
The reason I say, "classical free market," is to refer to the criteria for the invisible hand to function, according to Adam Smith.
There is no "criteria" for functional invisible hands. Smith was describing a
natural phenomena - producers will always produce where there is the greatest profit potential (maximize producer surplus), and consumers will always consume where there is the greatest savings potential (maximize consumer surplus).
This is true regardless of the composition of the market in which consumers and producers are participating. The monopolist is as subject to the principles of supply and demand as a competitive businessman. He faces a profit maximization problem, and will set his prices according to industry supply and demand functions, like any other business.
The only difference is that the monopolist has pricing power (or market power) - he does not take his price as given by the market. In perfect competition, no individual firm can raise its price (marginal revenue) above marginal cost without losing all of its customers to the competition. In perfect monopoly, an individual firm can raise its price above marginal cost without losing any of its customers
to the competition (but it
will lose customers to the substitution and income effects - customers will be willing and able to buy less of the more expensive good, aka the invisible hand). Most of the real world operates somewhere in between these two extremes.
Please note that a monopoly or oligopoly could be more or less "natural" depending on the factors that caused it to occur. If a hospital is a natural monopoly because various medical technologies used to be bulky and expensive and modern technology makes them less bulky and more affordable, numerous clinics could replace the hospital, even by housing them in the same general location, like a mall or city district.
Absolutely; the apparent dispute wasn't over whether or not man-made market failures exist (they do - licensing, zoning, and permitting are the obvious examples) but whether or not they arise naturally, in a "free market".
Yes, I think oligopoly is the most effective monopoly-type market control because slowly pricing out competitors, as you say, allows you to avoid regulatory interference.
It is not, discounting the value of avoiding regulatory interference. Absent collusion, an oligopolist will operate at a point where market price and supply are closer to competitive equilibrium than the monopolist, with greater aggregate social surplus but smaller producer surplus. The oligopolist will always prefer to be a monopolist, if possible.
The question then becomes whether they are truly free or controlled in some way. The only way to determine this is to look at the specific factors influencing producer and consumer behavior in a give situation.
No modern market is "absolutely" free, but a simple thought exercise can confirm the thesis. How do you imagine that the electrical generation and distribution industries would naturally come to be competitive? Would it ever be practical or economical for two competing firms to build redundant power plants servicing the same region, and to have every house and business in that region wired up to two or more redundant grids? Acme Power maintains the poles on the left side of the street, and Bravo Generation maintains the poles on the right?
The answer is, quite obviously, no. The market for electricity is naturally monopolistic, and there are no apparent competitive solutions. As a consequence, we treat them as publicly regulated legal monopolies.
