It's very complex academic question we have no answer to. I like to listen to all points of view, even those I do not support and those I oppose, to understand them, thus I have some kind of explanation here.

As I understand that, it's matter of resource management. There is huge ancap movement to replace monetary market with another form of social consensus, something like multi-money (some tokens to account for various resources and mechanisms to settle imbalances), or reputation engines (giving people with better chances of serving the common good more resources). "Good" ancap comes so close to other reasonable anarchy schools, that it totally sounds sane. It's a rare thing, often found only among the most educated capitalists and sympathizers.

Then there is just notion of understanding that imperialistic capitalism where resources concentrate in few actors hands sucks, and with better economical education The Free People should naturally resist it. Or die trying, well, naturally.

It is indeed a complex academic problem; yet I see popular ancap bs as theoretically redeemable through education (and practically, yes, I totally agree with the point of this drawing). Things are too screwed now to play these games, but rejecting a point of view altogether is not wise.
