It's insane to me that so many people seem to have a concept of legal loopholes informed entirely by like non-specific-pop-culture. As if it's magic incantations that get power to fuck off instead of like a purposefully built system.
Here's a hot take: all the sovereign citizens and equivalent in other nations are just the average persons general ideas about how the law works cranked to 11. Basically everyone believes in the magic incantation, they just overshot a bit.
