Some of you might find it peculiar, similar movements to Sovereign Citizens exist in many other countries, but they take different shapes depending on local cultural context.
For instance, in Russia there is a movement called "Citizens of USSR" who claim that since Boris Yeltsin in the 90s had no constitutional rights to change the name of the country from "Russian Soviet Federative Socialist Republic" to "Russian Federation" (which is actually correct, he didn't, not that it stopped him though), this change has never legally taken place, and "Russian Federation" is a placeholder corporation that occupies legally Soviet space. Why this can't be applied to RSFSR/USSR itself being "illegally" established on top lf 1917 Russian Republic, is a mystery.
Citizens of USSR even issue their own passports, however, their goals are exact same with Sovereign Citizens - tax evasion, ignoring traffic rules, and driving without a license.
I've used to do semi-competitive swimming as a child. Honestly one of the worst (as in boring, great for health and fixed my scoliosis) types of sport to do for an agitated child who wants to explore the world.
For an hour and a half you do laps while staring at the tiles on the bottom of your olympic pool. Would spend the entire time memorizing every crack on the tiles as well as doing entire video game playthroughs in my head lol
