There are some smoke and mirrors with the presentation and understanding of corporations. In reality, as you know, a "corporation" as it exists to day is a government creation (the fiat decree that allows the corporation to come into existence is a charter or license). Corporations are really just "government" warrants which place them farther away from an actual free market... especially through the displacement of liability (individuals are protected by government from the consequences that a single person not operating under the government shielding of "corporation" would not be protected from).
Corporations are another way for government to maintain control of who does business and to stifle undesired competition for goods and services it decides to maintain firm control on. Government only selectively regulates "corporations," ultimately to its own benefit (and more on point, to the benefit of it's chief influencers/owners).
The free market always regulates from the opposite direction, that is, rather than shutting out/regulating out competition... it always provides and open avenue for more new and better services and products to emerge in the gap left by bad business practices.
Such a free market always creates more value because it only ADDS value whereas government regulation always works by LIMITING value so that its favored "entities" can thrive without competition.
Thus, a free market, which always presents new niches of value, allows ANYONE who desires to work and improve his/her economic status to go forth and do so to the best of his/her ability and... to profit!
A regulated government environment, kills value and through taxation and distributed "free stuff" (to include any sort of UBI), it kills incentive to improve one's economic situation through producing more and better.
