Governmental regulation against corporations is, in theory, to protect citizens and societal values against the predations of greed and avarice that would cannibalize (consume) the very framework of trust and integrity upon which those economic markets are built.
The question becomes, does introducing new regulations reinstitute social values? Can you roll back into societal trust by muzzling sociopathic corporate appetites?
You see the conundrum: coercive limitation (force and power) allows for fairness, which provides the trust to participate with others. Or, networks of trust evolve, opening the opportunity for predatory behavior, which must be regulated with disciplinary measures. Either way, decency and fairness are fragile necessities for sociality, either manufactured by force or protected by coercive power, yet concomitant forces.
