"The term “free market capitalism” refers to an economy that puts no or minimal barriers in the way of privately owned businesses. Matters such as worker rights, environmental protection, and product safety will be addressed by businesses as the marketplace demands."
it's basically worship of owning the means of production and not being regulated in its use, e.g. if you own a company you get to dictate all sorts of unreasonable things to your employees, and any benefits gained from automation accrue to whoever can afford the up front money to own the machines.

Free markets never existed, don't exist and never will. Markets are defined by laws and regulations in which they exist in. They can't ever be "free".

Please get your definitions from someone reasonable (Adam Smith might be a good start) rather than Ayn Rand.
