My point is that a clearinghouse would seem archaic give defi and modern instruments, yet they still exist because history has shown they will survive times of crisis.
islamic banking may seem weird to you if you are even aware of it, but its a timeless archetype of a certain pattern of relationships and rules that arose in response to a certain envrionment at the time ( which persists into modern day ). this system has probably more in common superficially with crypto than some other ways of organizing economic activity.
using words like archaic shows ignorance of the subject and of humanity. maybe when AI is doing everything and new underlying dynamics exists for the way machines relate, we can have this discussion but even then scarcity and physics exist and some methods of resource allocation have to be negotiated or emerge organically.
