"which basically states that by merely existing in a particular geographical area, you are “agreeing” to abide by the rules of whatever ruling class claims it as their domain"

The above is only partially correct (btw: I love your writings), they use two levels of control, the first being contract which entangles 99%+ of us, such as Banking agreement, Drivers License, Passport, and any thing else where we 'agree' to be a Citizen (Subject). For the handful left over, those who are stateless, TPTB exercise authority over anyone who has not formed a 'compact'.
