This is all bullshit. Same with the "Corporation of the United States", all bullshit.

Nothing about the flag, physically or conceptually, has anything to do with laws or legality whatsoever. The notion of the flag at admiralty/maritime law is a figure of speech; there need not be a physical flag present on board to claim protection of a jurisdiction, just proof of that jurisdiction's consent.

Even if there is a such thing as a "Corporation of the United States", and perhaps there is, nothing about it has anything to do with laws or legality whatsoever. At best, it would just be a vehicle (one of many) for corruption and fraud to be perpetrated by persons acting under the color of law and/or leveraging their capacity as agents, officers, or other affiliates of the government.

"Dissolving the Corporation of the United States", if this is a meaningful possible act, and perhaps it is, would have zero bearing on any acts of the duly constituted government of the United States acting in its sovereign capacity. We can argue whether or not the government is (or has been) duly constituted, or if there's fraud perpetrated by persons in positions to wield governmental power, but any supposed "Corporation of the United States" (by whatever name the idiots give it) has no bearing on such argument.
