The Taliban will get bribes from the Chinese and Russians anyway. And sell heroin and fentanyl to make $$$$. And they "marry" women from the local subject population for a night or two. And ride motor scooters. Their needs are simple.
I think you are partly blinded by propaganda and sympathy for your American friends.
Last time the Taliban was in charge, they reduced the opium production in Afghanistan by 99%. They have said they will do this again.
It was the American allies that increased opium production.
While I do not generally put much value on Taliban announcements, I am not either valuing your predictions too highly.
