I agree with you to a certain extent.

However, a Kabul minister could just as easily argue that only a strong central government can prevent overpowerful local actors, i.e. warlords, from spinning off their own private domains and armies, especially given pushy neighbors like India, Iran, Pakistan, and Russia perfectly willing to fund local spoilers. This has happened numerous times in Afghan history, occasionally even seeing the localities overwhelming the center, as in 1929 and 1992.
