UTF yup your talking of a utopia.
Ok first with the money there is NO WAY aside from a govt to create a monetary system. Before govt there was barter then the ancient govts came up with money that represented something of equivalent value to avoid having to take 20 chickens to the next farm 10 miles away and get 2 pigs. If there is no govt creating the money you WILL end up with runaway inflation as someone WILL figure out to print their own and make themselves rich. Sorry HUMAN NATURE has showm 100% of the time that utopias WILL NEVER WORK!
As the the land thing again why is it your land?? because you live there?? possesion may be 9/10 of the law but ther eis now law without govt. So who says it yours you?? well me and the guy on the other side disagree, 2-1 we take your land. You either go peacefully or 2-1 chances are you will have a shallow grave. I'm not trying say I would do that but it only takes a very small percentage of the people to act in such a way for your anarchist society to become a true state of CHAOS.
Now if you first come up with a way to remove greed/violence/dishonesty etc.. from the human psyche there is a chance it could possibly work but then what would you do if any of these traits re-emerge???
I suggest you read The Dispossesed by Ursula K Leguin. She sets up a perfect utopian anarchistic society (I sense you will strongly agree with this society). Honestly it seems wonderfull for the first half of the book. Mind you she had to set it up on a different planet to make it work, then she shows all the flaws in this perfect system.
Note all these arguements are for societies larger than a small village. In a small village almost any type of govt or lack thereof will work as everyone knows each other and peer pressure to conform is increadily strong. Once you get to the size where everyone does not know each other it breaks down. Even in a village, if you get a psycopath or sociopath, well all bets are off.
