I think it’s important to distinguish “anarcho”-capitalist thought (which still needs a state to enforce private property and capital rights and generally doesn’t acknowledge the problems of monopolies, existing power imbalances etc.) and actual anarchist/anti-totalitarian policies.
All the things you mentioned except the last
(...) reduce central control, like charter cities, cryptocurrency and decentralised pandemic control
decentralise control from a democratic state to a moneyed elite, not to a more democratic state, confederation, anarchist commune or whatever.
From the perspective of every other lineage of anarchists, private property is one of the things that enforces injust hierarchies. Using that label is like calling yourself “vegano-carnivore” because you want to reduce the suffering of eating animals as much as possible while still eating them. Even if you can come up with a justification on it by presenting clearly realizable ways to implement this (e.g. lab grown meat), it is adopting a label from a community that does not want them to do so. Indeed, there was already a ready-made label “laisez-faire”, but that one has sufficiently negative historical associations that I guess it is to be avoided.
Regarding Friedman, I would challenge the statement that he provides ways to organize it without a state, given that he romantizices medieval iceland and the western frontier and I am highly skeptical that the law enforcement/military aspect required for enforcing capital right would not lead to the tyranny of the robber barons in their company towns again, but I would have to revisit it for detailed rebuttal.
