Sure, closed darknets are feasible. But open darknets are much more 
interesting. One of the HA group is also a member of a different darknet group, 
so the darknet grows; more generally, your friends and your friends' friends 
are generally not the same, so it is possible to have a large network in 
relatively few hops, this is the "small world effect". One key requirement is 
that there be many "short" links and a few "long" links, but what short and 
long mean in the real world is unclear; in routing terms, large differences in 
location, in real-world terms, probably a long link corresponds to a friend in 
a different geographical location, or a different occupation, or mostly 
different social circles, etc.
