I'm not a lawyer (though I am enrolled in law school, lol) but the entire thing is obviously fraudulent and wouldn't hold up in court.

The thing he/they/crown emperor of Mars or whatever cites is Article 1, Section 10 of the United States Constitution:

No state can ally with another country; make war; make their own money; allow private boats and vessels to catch and arrest enemy ships; or issue their own bills for credit. States must make only silver and gold to pay for things.

Like that's cool and all but he isn't a country, and one person does not a country make --

But then he cited the 14th amendment:

No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.

"Ahm, so uh -- you're claiming protection of a United States Citizen, then and recognizing the laws of the United States?" __

This guy will get the book thrown at him and they'll be laughing the whole time
