re anarchocapitalism: it doesn't imply lack of organization, nor how the organazitional structure gets formed.
its essence is a perspective on the legitimate use of force, on what principles should govern the use of force. and your quotes don't discuss any of that in the context of the bazaar prior to your offhand dismissal of the concept.
i.e. we don't know how close the organization and enforcement of the bazaar was to ancap priciples.
if e.g. all the enforcement were that you were simply not allowed to enter the bazaar until you complied, then it's fully compatible.
