Well, its a load of crap, but its a libertarian load of crap, not a liberal one. This is what happens when someone adopts a narrow set of premises and limits himself to working out everything from them and only them, applying rigid reason. Its a bit of an Aspergers approach.
Its a bit like the way the judicial reasoning of Sunni Islam is supposed to work, in their case the premises being the literal reading of their scriptures.
well said
