Nice picking what you want to read. Try reading the part where a free market isn't a monopoly, and both sellers and buyers argue over the price of goods.
There *is* government intervention. Cable companies are monopolies that are granted franchise rights to areas to be the sole provider in that area. That is hardly a free market.

When only two service providers exist in an area, those who provide what, in today's world, amounts to an indispensable service: they call the shots, not the consumer. Water companies could charge ten times what they do now and still keep most of their clientele, because people need water.

The free market only works in small, isolated communities. We're nation (and global) wide now, governmental regulation is necessary.
