I think this situation from the Spanish Revolution might provide a nice answer to some which could be said came from real practice and not from my intelectual anarchist theorectical genious. I mostly say i am neither a "green anarchist" with a green and black flag nor a red anarchist with a red and black flag but mostly a full black flag anarchist without adjectives who supports synthesis anarchism:
From the wikipedia article "Anarcho-naturism" http://en.wikipedia.org/wiki/Anarcho-naturism
"This ecological tendency in spanish anarchism was strong enough as to call the attention of the CNT–FAI in Spain. So Daniel Guérin in Anarchism: From Theory to Practice reports how "Spanish anarcho-syndicalism had long been concerned to safeguard the autonomy of what it called "affinity groups." There were many adepts of naturism and vegetarianism among its members, especially among the poor peasants of the south. Both these ways of living were considered suitable for the transformation of the human being in preparation for a libertarian society. At the Saragossa congress the members did not forget to consider the fate of groups of naturists and nudists, "unsuited to industrialization." As these groups would be unable to supply all their own needs, the congress anticipated that their delegates to the meetings of the confederation of communes would be able to negotiate special economic agreements with the other agricultural and industrial communes. On the eve of a vast, bloody, social transformation, the CNT did not think it foolish to try to meet the infinitely varied aspirations of individual human beings."
So neither primitivists can force us non primitivists to go hunter gathering and abandon agriculture nor can we force them to rely on things like automatic transportation, alternative energies, cities, towns, various technologies, or language (sorry but Zerzan talk againts language so i am not really making fun of them or something) and other things. Even today there are many hunting and gathering tribes and even uncontacted peoples in the Amazon Jungle, so in an anarchist society they will have a more confortable life with less pressure.
