Admiralty law exists. And it is used as the base of this conspiracy theory.

I enjoyed the parts that are true though, it was interesting.

That’s not a legal argument 

Try using that in a deposition or court 

you are under a spell :)

The origin of the maritime law conspiracy theory is unknown, though it may stem from a misunderstanding of some nautical-sounding words in common usage in the English-language judiciary such as ownership, citizenship, dock or birth (berth) certificate. This theory is entirely devoid of merit: when invoked by litigants, it has been consistently dismissed as frivolous.
