A corporation that has successfully achieved monopoly already has friends in government, or is just too good for competition. Be it the former, removing government will force it to collapse, letting actual competition win.
Be it the latter, someone with friends in government will screw them over. Screw those who want to deprive victors of spoils via arbitrary power.
There is no excuse for disrespecting the individuals personal rights to further corporate interests. If business want to succeed, do it the honest way, not by buying a police state. Like Monsanto farmers over bees intoxicating flowers with their crap gmos. Or regulations set up only to eliminate competition. Screw corporatism.
