Interesting. Is there a particular reason I can't answer questions here? Sorry, I am still new here.
Without meaning to sound snobbish, the simple answer is credibility. We've tried to avoid this thread becoming about either debate or grand-standing, which in the past seems to have been the result of an over-liberal policy on designating answerers. We want to explain rather than simply assert anarchist positions, and where possible to pull out all the messy complexities, ambiguities and points of tension within anarchist thought and practice, so it requires a certain demonstrated familiarity with these issues.
The difference between a suburb overlooking Silicon Valley and mud huts in Dhaka isn't 'social.' There are different opportunities, different means of power, both for states and other actors.
That's what I mean by "social context". An anarchist movement is a movement towards a reorganisation of how society works, so it depends on the social context you're starting with: on how power and resources are distributed, on the prevailing power relations, on the nature of work and workplace structures, and so on. You seem to be implying that anarchism requires a certain base-line of material development, and that's the classical Marxist view, but right now one of the largest experiment in self-government is occurring among some of the poorest peoples of the Western hemisphere, in the autonomous Zapatista communities of Chiapas, Mexico. We're also seeing the emergence of
self-governing communities in Syrian Kurdistan, which is a better plusher than mud huts but isn't quite Silicon Valley.
Does an anarchist society not require some medium of exchange?
Possibly, but not one that I would imagine transferring to a barter-system. To the extent that a stateless society adopts some sort of market or market-like mechanisms for large-scale problems (and it might; calculation problems are unfortunately A Thing), I think this would all be built around negotiation and trust, so any "currency", if that's even the word, would be about keeping a public account. It would be a matter of keeping reciprocal systems of behaviour transparent and roughly equitable, and if it stopped functioning as such, became a means of exercising power, then people could simply cease to recognise it, because it would after all exist only through consensus and not through the authority of any state. That wouldn't transfer to private bartering in any systematic way, even if we can imagine single off-the-books exchanges, because if it isn't functioning as part of a system of public account, it doesn't mean anything. (Further, I imagine that such a system would largely exist between communities or sectional organisations of some size- call them syndics, if you wanna get
The Dispossessed-y about it- rather than between individuals, who I don't imagine would have cause to trade with each other in any routine fashion. And what use would it be organisations like this to engage in a barter-system?)
There's a certain kind of anarchist that gets a bit too enthusiastic about bitcoin, but that might approach a sketch of an anarchist "currency", a way of formalising a system of "paying it forward", rather than about exchanging values. Bitcoin et al. are still structured as stores of value because they exist within a monetary economy, but if you take away the context of a capitalist society, I think we can see them acting a something more like digital wampum belts than as money in the conventional sense.
(At this point, Hygro is invited to explain how and why I'm completely botching the theory of money and should probably stop.)
Including coercion, correct?
Possibly. I don't have an absolute anti-coercion position. I think that it's a bad way to run a society, but if somebody is acting in an erratic and violent manner, I don't know how far they can be said to
be party of a society, just situated among it, like some sort of dangerous escape animal. I'd prefer people deal with the situation with as little resort to coercion as they can, but perhaps that wouldn't be possible.
How would an anarchist society handle large-scale projects, such as space exploration?
This is a very good question which deserves a more considered answer than I give right this moment, and I didn't want to just ignore, so I promise to get back to it when I get a chance.
