Subtracting the snark and the disapproving sniff, it is technically correct that a government's power to create and control a currency is one of the major fundamental differences between commercial businesses and government.

Remember that we tried using private currencies, plural, back at the dawn of America, while we were still mostly in experimental mode. That experiment showed that that way lies madness, and validated what had already been common practice for centuries: The money should be held by a neutral third party. Every gambler knows that commonsense principle.

It's a subset of the general premise that there must be separation between the marketplace, and the activities conducted within that marketplace. That is, for the marketplace to form a level playing field, the participants themselves, and especially one group alone, can't control it. To look for an analogy as far from politics as possible, consider the issues raised by Microsoft's 95% monopoly of computer operating systems...the supposedly neutral platform on which all other software must operate...while at the same time making other products that operated on that platform. It was shown that Microsoft had rigged the platform to favor its own products, and not just Web browsers.

The stock market pre 1929 gave the players virtually unlimited scope to game their marketplace and didn't bother to enforce any separation between investing and brokerage; and the players exploited the environment to the hilt. The combination of easy credit to buy leveraged stock with widespread manipulation by the "operators" is what made that marketplace collapse.

Seems to me that the basic question of whether the government should exercize oversight over marketplaces has been settled for a long time. We disagree over the degree of control that produces the optimum results, in part because traditionally the political parties have defined optimum according to the welfare of their core constituencies. And even the most pollyanish spin on capitalism acknowledges that sellers and buyers are natural adversaries.
