That wouldn't happen without power delegated from the government. We leave capitalism and free enterprise behind when that happens, yet still insist on using the same terms to label the consequences.

See also patent trolls, predatory DRM and copyright enforcement, and (often) the creation and maintenance of harmful monopolies.

The government's power is delegated by the people (and, in particular, people with influence, i.e., money). The power of corporations to direct government force is therefore inextricable from the power of corporations writ large, and that is derived wholly from unrestrained or improperly-restrained capitalism/enterprise. The government loses the power to abuse the public so intensely when corporations lose the power to abuse government, at least within a capitalist framework.

Capitalism has always been a creature of the state. Kings gave licenses to private individuals to invest, operate, and run public companies. Nowadays it’s more complex but the first step to create any public company is still to apply for a license. Power and money have always flown both ways. I suggest you look into the Muscovy Company. Created in 1555 as the first joint stock company, it was highly influential politically and relied on its political connections to earn profits. Nothing has changed in this regard for corporations since.
