You are right in what I think, a regulated market is not free. Either it is controlled by coercion, either it is not. The line is clear.
I did not know about the California electricity crisis, and I think your premise is that private companies did it on purpose or was provoked by speculation, and that state saved the citizen of such greedy bastard.
But the question to ask is why a private company would act against the interest of its customers, and thus loosing profit on purpose ? This is not a natural course of action of a market.
Let's talk about the "Megawatt laundering" problem of your link.
Cause :
My question is : who decided to control the price for electricity at the first place ?
My response is : government by coercion on prices... So how can you call this a market free ? It was not.
When gov imposes prices, there is 2 possibility.
Either the imposed price is lower than the natural price (the one without regulation), and in this case you provoke a shortage. (Because production go down)
This is what happened in this case.
I'll quote Milton Friedman :
Or, the imposed price is higher than the natural price.
This is what happens in some market like cabs, or even, minimal wages (that is regulation on labor's price).
And in this case, the demand drop, for minimal wages, you get more unemployment, and increased need in welfare.
In the case of Taxi, very few people are using cabs and preferring public transportation, and in the case of Ubber, lots of problem with legislation because it bypasses the imposed rate of taxi for the same service, which provoke injustice and stifle competition.
Let's talk about the "Overscheduling" problem.
So my question is : why the power line is handled by the state and not private companies ?
A private companies would have acted against such scam by making economically costly to reserve a line, preventing spam. But maybe law prevented that ?
If the cost of reservation would be too high, then another company, with its own power line would compete with it.
But no... the state, instead of acting as a rational economical agent, resort to MORE coercion of the kind that provoked the shortage in the first place. (price control)
Then one will say : what does prevent electrical companies to charge high price because of our dependence on energy ?
My response is: Competition by having multiple power providers. And if all abuse, the high price of energy would quickly fire economical forces to switch to alternative and less centralized source of energy.
Solar panel would become economically profitable and would spread very quickly.
This market was not free, and the failure of regulation, ironically provoked more regulation.
This is like the 1940 crisis... the fed created it with bad monetary policies, but instead of collapsing for its fault, it gained even more power by allowing to break the link with gold. (The failure of FED in 1940 was admitted by Bernake)
But during all this time, in all the school we were brainwashed to believe that greed of capitalism provoked the crisis, when it was not. There was no such thing as a free market when a central authority control the supply of money.
Here is an example:
No women are allowed to operate pubs and sell alcohol = not free market
Anyone is allowed to operate a pub and sell alcohol BUT it requires an alcohol license = free market & regulated
Utilities are an exception because the govt considers it a public necessity. The regulations are meant to the protect the public from price gouging. When regulations were lifted the prices for energy went up. So you may be theoretically correct that the govt controlled prices. But it was for the good of the consumer
Actually the energy shortage didn't come from govt control. It came from market manipulations after deregulation. You heard of Enron, no?
