"Secular leaders also did well. A notable example was the commander-in-chief of the Tibetan army, a member of the Dalai Lama’s lay Cabinet, who owned 4,000 square kilometers of land and 3,500 serfs. 12 Old Tibet has been misrepresented by some Western admirers as “a nation that required no police force because its people voluntarily observed the laws of karma.” 13 In fact. it had a professional army, albeit a small one, that served mainly as a gendarmerie for the landlords to keep order, protect their property, and hunt down runaway serfs.

Young Tibetan boys were regularly taken from their peasant families and brought into the monasteries to be trained as monks. Once there, they were bonded for life. Tashì-Tsering, a monk, reports that it was common for peasant children to be sexually mistreated in the monasteries. He himself was a victim of repeated rape, beginning at age nine. 14 The monastic estates also conscripted children for lifelong servitude as domestics, dance performers, and soldiers."

I think that the immediate liberation via Mao was quite important but I think you have a good point for a goal of the sustained revolution there.
