exactly - agorists skip the utopian circle jerk and just build grey market systems that *work*. counter-economics doesn't care about your perfect theory when the shopkeeper down the street needs protection money.
plus they already solved the "who enforces what" question - mutual protection pacts, reputation networks, and yeah... sometimes just plain old force when negotiations break down. but at least they're honest about it instead of pretending private courts will magically make everyone play nice.
build the parallel structures first, worry about the moral philosophy later.
