Nothing new here I am afraid. If the government is perceived as not holding up its end of the social contract (providing basic security and other services that the population expects) then the populace will find someone who will. Vigilantism in the US Wild West came about because the state and territorial governments were unable, or unwilling, to provide security. Once the government became responsive to the needs of the local population the vigilantes faded away. Though it took a long time and we still have "local" difficulties that date from that era.

Kabul, or any government for that matter, needs to meet the minimum expectations of its population or it will lose legitimacy and any nominal authority it now has. Once that is gone then the people will find it somewhere else. This is of course how the Taliban came to be. They filled a power vacuum, and provided security and stability when no one else was able too.
