No social system is likely to solve all problems of supply and demand, so you might find yourself in a long line once in a while in any sort of anarchist society. But the particular mix of corporate propaganda, sweatshop labor, planned obsolescence, etc. that lines people up for an iphone is probably a hothouse flower only sustainable by capitalism. Without large-scale, systematic exploitation you probably can't sustain the sorts of global production networks that make an iphone possible, and without capitalist property norms, there is unlikely to be much incentive to try. Market anarchism would depend on confronting what is clearly antithetical to anarchism in existing property and exchange norms, so if such a thing were to emerge it would almost certainly have very different incentives built into the economy. It's hard to predict the way those changes would shape things like consumer electronics, but the likelihood of a "decentralization" of demand seems pretty great. And quite a number of mutualists aren't even really "market anarchists" in any strong sense, and are likely to further complicate things by insisting on sustainability and applying ridiculously rigorous notions of mutuality to whatever shared norms exist. Pretty quickly, I think, the iphone scenario would just become impossible, at which point we would need to find other means to waste our days according to our needs and pleasures, and perhaps an anarchist approach that left plenty of room for both cooperation and market exchange might serve us pretty well there.
