Mmm. Sort of agree, but also sort of don't...
The rules emerge from first principles. Monopolies can't exist for more than a tiny moment in time, if the money is honest. Even now with dishonest fiat money, they exist mainly by the government giving them subsidies and regulations that raise the cost of competition.
I don't think prices need to be forced to be the same for each customer. If government isn't doing things to keep certain businesses dominant, then people will take care of that themselves by not being their customers and starting their own competing business.
