I don't think this is correct at all. What's called right libertarianism or laissez-faire capitalism emerged in the mid 20th century (e.g. Ayn Rand). It stole the term which had historically been a left term and simply cleansed it of its critique of corporate power.
Corporations are authoritarian, anti-democratic organizations that exercise a great deal of control over our economic lives. Laissez-faire capitalists saw an opportunity to use Left anti-authoritarian concepts to attack democratic state controls and regulations on corporate power. Often they will employ some mental gymnastics to redefine corporations as extensions of individual rights, hence the John Galt cult of personality stuff. This is akin to calling feudalism "liberty" because, think of the rights of kings. As such we have entered an era of unparalleled corporate power, control and concentration of wealth.
What exposes the sheer fraud of "right libertarianism" in Silicon Valley is that much of SV was created by the state and continues to be subsidized to the tune of billions annually. Look up DARPA.[1] So they're not even against state capitalism.
