Once again, you're letting your dogmatism get ahead of you. Central organization has consistently outcompeted federalized systems. This is clearly illustrated by the fact that pretty much all large companies are centrally organized. There is even a great example of Sears trying to compete with Walmart using a federalist approach which eventually drove it out of business.

Meanwhile, China shows how central planning allows dealing with pandemics effectively, how it results in great infrastructure such as cross country high speed rail, and how central planning allows actually tacking emissions instead of just talking about it. Market based principles you talk about in China are very much subordinate to the central plan.

Anarchists do not have practical approaches, if they did we would've seen them in action by now. It's been over a 100 years and all anarchists have done was to continue propping up the existing capitalist hellscape that whole time.

Anarchists share a lot with libertarians ideologically. It's largely a privileged class of people who largely don't care about actual suffering that's happening to people in their countries, and are more focused on high level concepts like freedom of speech because their own needs are already met. The "authoritarian state hell" you talk about lifted over a billion people out of abject poverty, but you can't be bothered with such things because you don't care about alleviating real suffering. Anarchism is fundamentally rooted in western individualism and selfishness. Anarchists can't imagine themselves as part of a collective whole and working towards common benefit. That's what anarchists refer to as authoritarian state hell.
