In Australia I knew I guy who was a SovCit and he would do stupid things like quote the bill of rights. We'd say "what bill of rights?" Australia doesn't have one. All his info came from the US and he just followed it with realising none of it was relevant in a different country.
True. But things like the UCC are real laws. Sovcits just hilariously misinterpret them. There is no such law in other countries. Plus sovcit stuff is based on common law. It makes even less sense in civil law jurisdictions.
Fortunately I haven't bothered keeping up with him for many years, but it wouldn't surprise me in the least if he was doing that. And protesting vaccinations too probably.
There is a similar movement to SovCits that is at least properly adapted to other countries (specifically the Commonwealth and Ireland's) laws called "Freeman on the Land."
that would of course be count Binface, who is a space alien and thus obviously is only subject to any human law in so far as that he chooses to go along with it.
in general, things do exist out of the U.S, its just people in the U.S do it more publicly. Its like racism, and how some people think U.S is the most racist due to media and social media, its actually very far from that on the general scale of things when compared to other countries.
