Anarchism has had more influence in Spain than anywhere else Stan. The short lived collectivization of land and factories by the workers themselves in large parts of the country, but particularly in Catalonia before being crushed by the combined forces of Franco, on the one side, and the, Soviet influenced, Communist forces on the other. This is the only example I can think of from modern times. There still is a larger concentration of worker's cooperatives in Catalonia and the Basque regions than anywhere else. Prior to that most social experiments of this nature would have had a semi religious nature. People always tend to think that 'Communism', as an idea, started with Marx - it didn't. For about 2,000 years all Communist experiments had had a religious context - Fra Dolcino, Gerard Winstanley, Thomas Munzer etc.etc. And this is not confined to Christianity - the first welfare state, and unconditional income for all citizens were established by the first Caliph after Mohammed. You are right that anarchic movements have tended to be small scale - of course, they start from below and not from the level of the state as such. They have also tended to have another unifying belief such as a religion. Is a Christian Anarchist really an Anarchist when he says that all authority stems directly from God ? If so then most Quakers are Anarchists, and this group has had a decisive influence on politics, in the abolition of slavery, recognition of conscientious objection, establishment of organizations such as Greenpeace, Amnesty International etc.
I cannot quote an 'ideal' society - I can say that there are some things about some systems which I admire (the decentralization of Switzerland for example). But what I can state categorically is that we need to rethink our relationship to consumerism. To stop saying that 'growth' is always good, and consider that we may be producing enough already and that what is now needed is a fairer distribution of resources.
