Probably no one has ever "taken you up on this" because the body of literature on Anarchy is enough to be a library on it's own. Since you've somehow managed to miss it means you're unlikely to read anything anyone would point you at.
It's heavily cited so you can go as deep as you care to.
P.S.: The short answer is: the "gang warfare" scenario comes from bartering, whether with money or direct bartering (e.g. trade 100 loafs of bread for a bicycle). For Anarchism to work, you'd need to get rid of capitalism and bartering completely. Think Star-trek.
Also note, I'm not arguing for anarchism but rather against ignorance. I personally don't think the world is ready for anarchism but at least I know what it actually is.
But for anyone else who might happen on this comment and be truly curious, here's a good starting point: http://theanarchistlibrary.org/library/the-anarchist-faq-edi...
